Chapter Text

Donnie sat at the kitchen table hunched over his favorite purple mug, wearing his softest royal purple hoodie that was two sizes too big, hood pulled up to hide his face in shadow, hands pulled inside of the sleeves. His legs were practically swimming in matching sweatpants, his feet stuffed into fuzzy socks custom knit by Raph to fit his feet comfortably without any irritating seams. He slurped loudly, made a disgusted noise, and drank more.

Raph walked in just as Donnie made the most pathetic sound, a particularly wet sniffle followed by a pained whine. He watched as his younger brother took a tissue out of the big pocket of his hoodie and blew his nose, then a metal appendage came out from beneath his hoodie and took the used tissue, incinerating it.

“Donnie, what did we say about usin’ fire when you’re not feelin’ well?” Raph chided, coming over to yank the hood down to get a good look at the softshell’s face.

Donnie flinched, caught himself before he could fall off the chair, and hissed before his rational brain could stop him. His eyes were red rimmed and wet, squinting from the sudden light exposure. He wasn't wearing his mask or goggles, so Raph was pretty sure he had a headache, and his face was flushed in a way it rarely was unless he had a fever.

Plus, judging from the revolted expression as he took yet another sip from the mug, he was drinking Splinter’s special herbal tea blend they only drank when they got sick, which tasted horrible.

“Uh…don't get caught…?” Donnie croaked, wearing a nervous smile in spite of his discomfort.

Raph sighed and picked up his brother, carrying him toward Donnie’s bedroom, making sure to hold him upright so as not to spill the liquid in his mug. Donnie protested loudly, drawing the attention of Leo and Mikey, who came running.

“No, Raph, put me down! I’m fine! I don't need to go to bed!” Donnie broke off with a round of coughing, followed by a sad chirp.

“Yeah, buddy, I'd totally buy that, except ya sound awful,” Raph responded with a sympathetic pat on Donnie's back. “Which reminds me. Take that battle shell off.”

Donnie grumbled but complied, releasing it and letting it drop out of the back of his hoodie. Leo ran up to catch it.

“Don’t worry, twinsie, I’m just gonna set it right here!” Leo reassured him with a grin, placing the valuable piece of technology on top of the small desk in the corner that Donnie rarely actually used.

Raph set Donnie down in bed after he pulled back the covers, and the softshell looked up at his big brother with pleading eyes.

“Raph, no, I don't want to go to sleep!” Donnie whined. “I can't. Don't leave me here!” His eyes snapped over to his other siblings. “Mikey, my favorite baby bro, back me up here! I don't need to be in bed. I can rest perfectly fine on the couch or–or in my lab!” He looked at Leo. “Nardo, tell Raph you won’t leave me alone so he doesn't have to worry about me!”

Mikey walked over and threw his arms around Donnie in a hug, and Leo climbed into bed to pin his twin down in a horizontal position.

“Trust me, bro, you’re gonna feel so much better when you've had some actual sleep!” Leo soothed, nuzzling Donnie’s cheek.

Donnie was starting to relax against his will, a tired churr rising. The physical contact felt nice. Just as he was giving up the fight, Mikey let go and Leo got up off of him, assuming they'd won.

Donnie tensed up and grabbed both of them by the arm, too exhausted and sick to put up a front. His lip wobbled and he gave them the saddest puppy dog eyes.

“Please don't leave,” he begged, voice cracking down the middle, “I can't be alone or they’ll get me!” He sneezed, and his whole body shook with the force of it.

“Aww, Dee!” Mikey reattached himself to Donnie, getting under the covers to cuddle with him properly. “Don’t worry, nothing's gonna get you! We're right here. Right, guys?”

Leo’s expression softened, and he snuggled against Donnie’s other side. “Of course, bro, we’re staying right here!” He smiled at Raph. “Hey Raph, can you get us the laptop and some snacks and drinks? I think it's Jupiter Jim time!”

Raph wanted to argue, but he could see Donnie melting into their touch, eyes starting to glaze over as Leo and Mikey’s cuddles worked their magic. He went to fetch the requested items, and by the time he got back, Donnie was snoring faintly, his head resting on Leo's shoulder.

“Aww, poor guy,” Raph whispered, smiling. “Glad I didn't get stuck. I’d join ya but, y’know. Too big.” He smirked. “He's a cuddle bug when he’s sick.”

Mikey beamed. “He just needs a little extra love!”

“I wonder what he meant,” mused Leo. “He said ‘they’ll get me.’”

Behind them, hidden among the pillows, a pink tentacle wriggled. Waiting.

Mikey and Leo stood naked in the medbay, while Donnie knelt on the tiled floor and examined them carefully. He probed their slits with gloved fingers, lifted their tails to inspect their backsides thoroughly, and squeezed their thighs firmly just to feel their muscle tone.

“Excellent, you both appear to be in peak health. Now, I’m afraid I must ask both of you to drop for me so I can check your cocks for any abnormalities. Don’t worry, it's highly unlikely, just a routine exam.” He patted them both lightly right over their slits, and got rewarded with soft grunts as they each dropped into one of his hands.

“Nice, no visible defects or signs of any disease. Hold still, please, while I perform a manual examination. It's fortunate that I have two hands and I'm fairly ambidextrous, amused chuckle. I can perform two exams at once. Very efficient, if I do say so myself.”

Donnie changed his gloves, pulling a new pair on with a loud snap, and squirted some lube on both hands before wrapping them around his brothers’ cocks. He stroked them experimentally, feeling them grow engorged in his grip. Both brothers bit back moans.

“Fascinating. Don't hold back; I’d like to hear how you react to my touch, for science! Michael, your cock is both larger and girthier than Nardo’s. Both of you are growers, but you have a disproportionately larger member. Sorry, Leo, I’m afraid that you're simply not as well endowed as our baby brother. But do you know what that means, my dear twin?” He grinned, watching Leo’s eyes grow unfocused as his hips twitched.

“W-what?” Leo panted, reaching a hand out toward Mikey. The box turtle grabbed it immediately, holding on tight. Leo was blushing, both embarrassed and aroused.

“It means that you have more nerve density in every inch, Nardo,” Donnie informed the slider in a deeper, sexier tone. “So when I do *this*, it’s easier to make you fall apart faster. Because you're so beautifully responsive.”
He squeezed and stroked both of them from base to tip steadily, using his thumbs to tease their glans, tracing shapes over their most sensitive flesh.

Both turtles whimpered and chirped, but Leo was overflowing with precum, already well on his way to his peak.

“Look at that, Mikey. Look at how close he is,” purred Donnie. “Isn’t he beautiful?”

Mikey let out a shaky moan and turned his head, reaching to cup Leo’s face with his free hand, kissing him hard.

It didn't take much longer before Leo was leaning into Donnie’s touch, erupting in big long spurts, growling into Mikey’s mouth. And when Mikey came too, Donnie felt himself drop into his shorts. He knew without a doubt that it was time for some more *personal* experimentation.

He quickly took off the gloves, facing away from his brothers so they didn't see him tasting what was on them.

“You are both very healthy. Congratulations, you are free to go! Would you please send Raphala in on your way out?” Donnie requested, glancing back at them with a big excited smile.

Mikey and Leo both smirked knowingly as they cleaned up and left. Donnie waited impatiently for his big brother.

Raph walked in with a little extra swagger, winking at Donnie as he locked the door behind him. He pulled off his shorts and let his huge barbed length drop down. It was the size of Mikey's forearm, and it made Donnie soaking wet with slick and precum at the sight. He couldn't pull his own shorts off fast enough.

“Get inside of me, Big Daddy!” Donnie begged, stars in his eyes.

He’d been stretching himself out earlier, with lots of lube and a big dildo, and he was wearing his biggest plug. Raph picked him up and bent him over the edge of the exam table, tugging out the plug and setting it aside. He lined up with Donnie’s ass and pushed in with a deep churr.

Donnie hissed and chirped noisily as Raph filled him up in a way their other brothers couldn't. It wasn't their fault. Donnie just needed his Raphie to do the job. The size difference was so satisfying.

He couldn't be too rough, but this was something they’d worked up to with lots of practice, and the snapping turtle knew exactly how fast and hard he could fuck Donnie’s brains out. So he went slowly at first, then picked up some speed as the softshell relaxed into it. They took their time, building up their pleasure, and when they came, Raph made sure to push the plug back in after he filled Donnie up with his big load of cum.

Sure, Dee would be a little sore, and they would probably have to take a day off from patrol. But he was proud of having satisfied all three of his brothers, and he felt amazing.

Maybe he should play doctor more often.

Chapter Text

“Are you sure he can't–” Raph blurted, fear stink filling the air in the whole room.

“He’s completely inoculated. Harmless.” Donnie’s tone was clinical. Even. Not revealing anything the softshell might be feeling, or shoving deep down so he never, ever had to feel it again. He’d aged so much in the past few days. His eyes were empty. Hopeless.

“Can I–Dee, can I touch him? Will he bite me?” Mikey’s voice held all the emotions Donnie couldn't express right now. If Donnie let himself feel any of it, he would fall apart into a million pieces. Mikey, though. Mikey was resilient and flexible, used to the waves and gusts of strong emotion. He could cry and scream and rage, and bounce back in time to save the day. If there were any way to save this one, Mikey would find it.

Donnie crouched in front of what was left of his twin, his love, his entire body rigid with tension, ready to flee or fight or maybe just freak the fuck out, if only he had the energy. He hadn't slept in days. Not counting micronaps.

“You should be safe,” he stated reluctantly. “Do not let him pull you away from us.” He cupped Mikey's chin roughly, staring into his eyes intensely. “Do not. We need you.”

The combination of Mikey’s reassuring smile and the flood of tears that spilled down his face made something in Donnie recoil. “I'm not going anywhere, Dee!”

Donnie let go of Mikey and stood, stepping back. He pulled out his collapsed bo and activated his ninpo. It glowed and extended to its full size. Just in case.

Mikey sank down to his knees and held both arms out to Leo. The slider, dead 3 days ago and 2 days undead, made a throaty hissing sound and inched forward on his leg stumps. When their bodies met, Leo's cold, stiff arms lifted and tried to close around Mikey’s body, but his elbows would no longer bend.

Mikey embraced him, shaking, starting to sob quietly. “Leo! I miss you! I don't want to give up on you!” He hid his face in Leo's neck for a moment. Donnie watched, holding his breath.

“Hhhhhhh,” Leo vocalized, and Mikey wondered if he was trying to shush him, soothe him.

Mikey pulled back to look at Leo with blurry eyes. Two things happened in rapid succession.

Leo lurched forward, mouth open, aiming for Mikey’s head.

Donnie made an angry, despairing noise and rushed forward to knock Leo to the ground, and used his bo to bash him in the head over and over with an ugly crunch and a wet sound as his skull caved in and his brain became nothing but meat splattered on the concrete.

Raph turned away and threw up.

Mikey wailed, devastated.

Donnie deactivated his bo. He stared at the once again dead corpse of his twin, the reanimated thing that had worn his Leo’s face, and forced himself to really look at what he’d done. He’d only had seconds to decide if Leo was a threat, if he was about to lose another brother to this horrible plague that was stealing people’s bodies and ruining everything.

He focused in on Leo’s mouth, still wide open. And his whole body turned ice cold.

Leo’s teeth were gone. Every last one, removed from their sockets. In the chaos, Donnie hadn't seen that detail, and he realized that even if Leo had tried to bite Mikey, he wouldn't be able to break the flesh open.

A vision: Leo, in his last moments, reaching for Mikey to reassure his crying baby brother, leaning in to kiss his forehead.

Donnie had rewarded that with a death sentence. The Cain Instinct. He couldn't be 100% sure, but he thought maybe he was a murderer now. Fratricide.

Donnie fell to the ground and screamed. Everything he’d been keeping inside came rushing out. Tears, snot, even a little puke as he hovered on his hands and knees, filthy, unworthy of being alive anymore. He was a monster, and no longer a twin.

His Leo was lost forever.

Everything went black.

.

When Donnie returned to consciousness, he was wrapped in gold chains, sitting hunched over on a rooftop, in the middle of a chalk circle filled with runes and candles. The rooftop. Metro Tower.

Raph and Mikey sat on either side of him.

“Good, you're awake,” Mikey said in a raspy voice. Calm. Much calmer than Donnie deserved. He withdrew the chains. “We're gonna talk to Leo’s spirit.”

“You did your best,” Raph told him in a sad, understanding voice. “It was mercy.”

“It was Leo,” Donnie choked out past the lump in his throat.

The candles lit despite all the wind on the rooftop. The runes glowed. Mikey glowed. Donnie and Raph were pulled into the mystic realm.

Leo appeared in a white room of nothing, just pure blinding light. He had a blue aura, and he looked unblemished. Perfect. He could have been alive, if they didn't know better.

He headed straight for Donnie and crouched down to pull him into a hug. Donnie whined and held on with all of his strength.

“It's ok. I would have done the same thing,” Leo whispered. “No hard feelings, Dee. You were protecting Mikey.”

Donnie sobbed into Leo’s neck. He wanted to apologize, to tell him he loved him, but he couldn't get the words out.

Leo understood anyway. He sat and pulled Donnie into his lap and rocked him.

“Shhhhhh,” he soothed, kissing him in the middle of his forehead.

Chapter Text

Tella woke with two fingers buried in her cunt and the sensation of every muscle and nerve in her lower body singing with pleasure. She churred and wrapped her long legs around Donnie, who was fucking her rhythmically with his right hand while holding her open with the other and giving her clit soft kitten licks.

“Donnie!” she moaned, voice trembling. Her purple clit flexed and twitched like a tiny version of Donnie’s cock, wiggling against the tip of his tongue. He giggled between her thighs, and flattened his tongue, lapping.

“Ohhhh fuck,” she growled, eyes squeezed shut, teeth sinking into her forearm as she slowly ground against his tongue and hand. Heat spread through her whole body, her abdominal muscles tensing, and she gushed down his chin as she came helplessly. “Aaaahhhh!!!”

When she was finished, eyes half lidded and chest heaving, she relaxed her legs so Donnie could move. He wiped his hand and face, and flopped down beside her, face down, tail in the air.

He tried to hide it, but Tella could see that he’d dropped, and his thick cock was leaking a steady puddle of slick and precum onto the sheets.

“Oh, Sweetness. Let me help you,” she purred, rolling onto her side.

She dipped her fingers into the well of liquid at the tip of Donnie’s cock, and he let out a startled cry, his petals opening at her touch.

“Love. Do you want me to fuck you with my fingers like you did to me?” she whispered right up against his tympanum.

Donnie nodded frantically, spreading his legs and lifting higher as Tella’s lubed up fingertips found the tight pucker at the base of his tail and began to massage him there.

“Good boy,” she praised, voice syrupy sweet and full of love. “Here, let me just–” She moved suddenly, getting her head under him and squeezing his thighs as she settled him into place right over her face. A few more swipes of her hand over his needy cock and she plunged two fingers into his ass, finding him already stretched and ready.

Donnie groaned with need and rocked against her hand. He shuddered as she licked his dick like an ice cream cone, catching all the little drips as she took the tip into her mouth.

She held his length in one perfect, slightly calloused hand, humming appreciatively, and then swallowed him down until he was nestled deep in her throat. Her hand, now free, reached back to massage his tail while she fucked him slowly, twisting her fingers inside of him. He could feel her knuckles nudging against his prostate, sending shocks of pleasure through his body.

Donnie looked down at Tella, meeting her eyes, questioning. The corners of her eyes crinkled even as tears welled up and began to roll down the sides of her face from the strain of keeping her jaw so wide open. Drool built up and started to leak down her chin as well. She winked at him and let go of his tail long enough to finger spell ‘Fuck my throat’, and well…he needed no further encouragement.

Donnie grunted and churred as Tella sped up her efforts inside of him. He withdrew almost to the tip and then began to thrust into her mouth, using her for his pleasure. And soon she was churring too. She seemed to enjoy the sensation of him, and judging from the way her tongue tried to swirl around his shaft with each stroke, his musky flavor did it for her too.

Tella’s thumb slid into Donnie with an audible wet pop, and the added pressure made him see stars. He toppled over the edge without warning, shooting ropes of cum down her throat, shuddering as she swallowed with him still deep inside. He let out moans and chirps that he was glad no one but Tella would hear, because it was all so embarrassing, the way he lost control so loudly.

Tella continued to fuck him steadily until he was emptied out, and she only released him because he was losing the ability to stay upright. She wiped her mouth and cleaned both of them up, letting him lie next to her with his head resting over her breasts afterward.

“Good morning,” she grinned.

“Best morning,” he agreed, a little dazed.

“How–FUCK–much longer?” Donnie groaned, ass and pussy out, bent over with both hands clamped between his legs, doing a restless bounce on his toes then immediately regretting the move as it jostled his throbbing bladder that made his plastron bulge out with the weight of 2 ½ liters of flavorless juice.

He’d been waiting to use the bathroom all day. First his personal toilet in the lab had literally decided to rebel just after mandatory family lunch (Mikey was getting heavy handed with meal enforcement lately), having somehow developed sentience overnight and deciding it was too good for Donnie to use as a waste receptacle. Then, when he couldn't talk it into compliance, he went to use the main bathroom, only to find that Raph had broken the doorknob and no one could get in or out. With an exasperated sigh he’d manifested the necessary tools to liberate Raph, and his big brother had been so grateful that he’d given the softshell a big, bone crushing hug. Which, under any other circumstances, would have been great. Donnie loved Raph’s firm pressure hugs. But at that point he was already getting uncomfortably full, and he had to subtly press his thighs together to stop the urge that nearly overpowered him at that moment.

He'd managed to delay for a couple more hours, but every time he tried to get into the bathroom, someone or something got in the way. He’d tried to restrict his fluid intake, but while he was waiting out Leo, who’d decided now was the perfect time for an hour long soak in their luxurious Raph Sized bathtub with the hot tub function that would massage his shell with jets of soothing hot water–nonono, fuck, Donnie was not thinking about the way it would feel to release the contents of his bladder in a similar way–followed by his lengthy skin care routine, Mikey had shoved a bottle of ice cold water into his hand and told him he needed to hydrate or else.

One simply did not argue with Mikey when there was the possibility of Doctor Delicate Touch as a consequence.

Donnie had drained the bottle quickly under his baby brother’s watchful eye, and he could have sworn he saw a tiny smirk on the box turtle’s lips before Mikey produced an approving smile and left.

Now, after six hours of holding his bladder and counting, Donnie was starting to lose the battle. His nerves were frayed, his urethra burned and was starting to twitch from the effort of keeping back the deluge, and he was on the verge of tears from the certain knowledge that he was about to piss on the floor like a helpless little baby.

“C’MON NARDO!” he yelled, voice cracking. “PLEASE! I REALLY, REALLY HAVE TO GO RIGHT NOW!” He crossed his legs tightly and looked around frantically for literally anything he could piss in. Unfortunately there was nothing he could use, except for that big expensive vase over there that was a Hamato family heirloom sent over from Japan the last time Splinter had traveled there to find some missing scrolls.

Oh Spirits, forgive me, he thought.

“Almost done!” he heard Leo say cheerfully, taking his sweet time that Donnie simply did not have. Unless they wanted him to make a big puddle on the floor, desperate times called for desperate measures.

He moved as fast as he could without taking his hands away from his leaking slit (and he was embarrassed to admit that most of that moisture was slick) until he was straddling the vase. Then, in a motion so fast that it was a blur, Donnie moved his hands out of the way just in time for a thick spray of nearly clear liquid to shoot out of his pee hole into the large vessel.

The noise was loud, the hard jet of urine splattering along the sides of the vase and pooling at the bottom. Donnie exhaled a relieved gust of air and closed his eyes, losing all sense of the world around him.

A round of applause and wolf whistles snapped him out of it and made him burn with humiliation. He opened his eyes to see Leo, Mikey, and Raph all grinning at him, watching as the stream left his body.

“Gotta say, Dee, I'm impressed! You held that much liquid for waaaay longer than even Raph could with that massive bladder of his!” Leo remarked, moving in close to rub the residual bulge that his bladder had left protruding from his plastron. “That's really hot!”

Donnie whimpered, hiding his face, still pissing and unable to control it. “You all set me up!” he complained. Behind his hands, his face crumpled and he let out a pathetic hiccuping sob. “You–you know I hate it when you do that!”

Leo's voice grew softer as he moved his hand lower, holding Donnie's pussy open with his fingers, aiming the spray so it shimmered in the low lighting of the lair.

“But you love it too,” he mused, kissing Donnie’s shoulder lovingly. “You love it when we make you feel so much you can't control yourself. You love it when we watch.” As Donnie’s flow tapered off, Leo carefully blotted him dry with a soft cloth he’d summoned from somewhere with a small portal, and dipped his fingers between Donnie’s folds.

Donnie shivered and didn't fight it when Raph came over and picked him up with a low growl, and Mikey reached up and rubbed his ass, and Leo kept fingering his pussy the whole way to Raph’s bedroom.

As they all took turns eating him out and fucking him thoroughly, he had to admit that in this case, Leo wasn't wrong.

It was too bad about that vase, though.

Chapter Text

“I’m doing this because I love you. I promise, you won't feel a thing. I anesthetized the area so you should feel numb in that spot. I don't actually believe that people should suffer, if they're in love. It's simply unnecessary in modern times. Now, hold very still so I don't accidentally cut the wrong tissue by mistake. Now *that* would hurt. Amused chuckle.”

Leo, restrained in an old dentist’s chair in the back of the medbay, gagged so he wouldn't try to distract Donnie from his task or yell for help, whimpered in fear, eyes glued to the scalpel in his twin’s hand. He could barely move.

Donnie looked a little intimidated by the task at hand, but he stared into Leo's eyes with such devotion and bravery that the slider almost caved and let him continue. After all, Donnie was about to slice into his face, which involved blood and all sorts of icky things. And then he was going to eat a piece of Leo's face, as proof of his love for his twin.

In a sick, twisted way, it was romantic.

Leo came to his senses a second later, and did the only thing he could think of. He mind melded with Raph, sending an SOS with a visual of where he was and exactly what Donnie was doing.

In his haste to stop the softshell, Raph broke down the locked and reinforced medbay doors. Eugh boy, that was gonna be a pain to fix.

“DONNIE! STOP WHAT YOU'RE DOING RIGHT NOW!” Raph shouted, running toward them, Mikey trailing after him.

Donnie dropped the scalpel back on the instrument tray and spun around, hands in the air, eyes wide and innocent.

“But Raphie, we’re in love!” Donnie proclaimed, slowly moving one hand to undo the gag so Leo could speak. “Isn't that right, Nardo?”

Leo made a face, working his jaw for a moment before responding. “It's true, guys, we are in love. I don't quite understand why that means Donnie has to engage in some light cannibalism, but he's never really needed a reason for that.” He smiled sweetly. “Donbon, before you eat my face, do you think you could explain why?”

Raph and Mikey both relaxed, and Donnie looked back at Leo sheepishly, one hand on the back of his neck.

“Oh. I’m…sorry, Leon, I thought you knew. Quoting Raphie here: when a mommy and a daddy are in love, the daddy has to eat the mommy’s face. It might look scary but they both really like it. It shows how much the daddy loves the mommy. End quote. I know we're not exactly a traditional couple, Nardo, but I really, really want to spend the rest of my life with you (that's two reallys) and I wanted to prove that to you.” He sounded so sincere.

Leo and Mikey both stared at Raph. “You said WHAT?” Mikey said, eyes bugging out.

Raph started to protest, then remembered something from when they were kids. Watching one of Splinter's telenovelas and witnessing two of the characters kissing, he’d thought they were attacking each other and asked his dad about it. Splinter had given him some vague answer about mommies and daddies eating each other's faces, “and that's why little turtles should be playing with their brothers and not watching Daddy's stories. You are too young for this stuff. Run along!”

When Donnie had asked him about what he saw in one of the Lou Jitsu movies, Raph had dutifully passed on their father’s wisdom, not thinking. Later, of course, he’d learned what kissing was, but he hadn't realized Donnie would still believe that old story so many years later.

“Ohhhh, that's my bad, sorry guys,” Raph muttered, ashamed. “Donnie, that's not really a thing. It’s just somethin’ Pops said to shut me up when we were kids. Leo knows ya love him. That's good enough.”

Donnie went pale. “But…wait, you mean I almost–” He clamped a hand over his mouth and ran to the bathroom. Vomitello made an appearance.

Mikey and Raph unfastened the restraints, and Leo sat up. He was quickly pulled into a hug, held tightly by both brothers.

“Are you ok?” Mikey asked, giving him a worried look. “Do you want me to get Doctor Delicate Touch to kick his shell?”

“I’m fiiiine!” Leo laughed, although sweat was beading on his forehead. “C’mon, we've all been bitten by Donnie when he's in a mood. I didn't even lose any scales this time!”

The toilet flushed, and they heard vigorous tooth brushing and gargling before Donnie emerged, looking guilty. He approached Leo, unable to make eye contact.

“I am so, so sorry for almost torturing you!” Donnie blurted out sadly.

Leo wiggled his way out of Raph and Mikey’s arms and grabbed Donnie by his short mask tails, pulling him into a soft kiss.

Donnie relaxed into it, holding onto Leo like he was afraid the slider would disappear. When the kiss ended, he finally met Leo’s eyes, only to see him grinning.

“I can't believe you and Raph thought *that* was cannibalism!” Leo laughed.

Mikey giggled. Raph and Donnie both blushed.

“I promise I will examine my assumptions before trying anything so drastic in the future,” Donnie said slowly.

“Thanks,” Leo exhaled, before pulling him in for another kiss.

Chapter Text

“Come on,” Leo coaxed, a wide, reassuring smile on his face. “The water’s nice and warm, there's like…soap crayons? So if you get some inspiration you can create a masterpiece! And I promise I won't let you go under.” He reached out with both arms, already naked and waiting, half submerged but up on his knees so he could help Mikey into the bath if the box turtle wanted. And it wasn't like Leo hadn't made everything perfect, because if it weren't for his hindbrain insisting there was danger, Mikey would have already been in there with his sexy, adorable big brother.

It wasn't a rational fear, but Mikey was shaking. He was so afraid right now. He didn't want to go in. He wanted to turn and run away, go hide in his room and….

Mikey looked at his handsome Leo, who would never let any harm come to him, and he took a few deep breaths. Then he took Leo's steady hands and held on as he stepped into the water.

Oh, it was so warm and inviting! His brain immediately went quiet as it realized he wasn't in danger. The water wasn't ice cold and biting and threatening to pull him under the waves. He was safe with his brother like when they were babies and Splinter would put them in a few inches of water and let them play while he washed them.

Mikey started to cry. He couldn't help it. He hadn't felt like this in years, not since that day when they were fighting that sea monster mutant by the docks and he’d gotten pulled far away from his brothers and almost drowned. He could still remember what it felt like to be dragged underwater, the sensation of icy cold water all over his body and in his throat. And he remembered suddenly, Leo was there. Leo had portaled him out and helped him warm up and breathe.

He threw his arms around Leo and hugged him hard, sniffling. Leo caught him and embraced him, humming something under his breath, churring.

“Thank you,” Mikey warbled. “You saved me then and you're saving me now! I love you!”

Leo kissed his forehead. “I love you too, Mikes. You're so brave! I’m proud of you!” He was smiling so big.

They held onto each other for a few minutes, until Mikey felt calm enough to let go. Leo drained a little of the water and added more hot to warm it up, and Mikey added some bubbles. Then they took turns drawing on each other with the soap crayons.

Half an hour later, Donnie came in to check on them. The tub being Raph sized meant that he could also fit, and he was only wearing a hoodie with nothing underneath, so it was easy for him to undress and get into the water with them.

He wasn't in a talking mood, but he turned his carapace toward Mikey in a clear invitation. Mikey spent a good ten minutes decorating his shell with doodles of the Genius Built™ logo and various plants that Donnie liked. After he finished, Donnie reached for his hoodie and pulled out his phone so Mikey could get a photo of his art.

They all washed each other, and then Donnie and Leo held Mikey between them and fucked him, Leo taking his pussy and Donnie taking his ass. Mikey felt so full and overwhelmed by all the attention. There wasn't any room for fear anymore.

Donnie was churring and growling, hands roaming all over Mikey's plastron. Leo kept up a steady stream of dirty talk right up against his tympanum, telling him how good and tight his pussy was, how he wanted to fill him up, how fantastic it felt to be fucking him and feel his twin’s freaky dick through his vaginal wall. Leo’s words were getting Donnie more worked up as well, and they both sped up their thrusts, sending Mikey hurtling over the edge into an intense, squirting climax. Donnie and Leo both came inside of him within seconds of each other.

Raph walked in on them as they were finishing, and he just stood over them and stroked himself until he came all over them. The trio could only watch, salivating at the sight of his cock, moving toward him so they could catch some of his cum on their tongues.

They drained the tub and all four took a few minutes to shower. Then they dried off and headed for Raph’s room to cuddle and watch funny videos.

“Guys,” Mikey spoke up from his comfy spot on Raph’s shell, “thanks for helping me. Maybe next time we can go to a lake or something? I miss swimming with you.”

Donnie patted Mikey’s arm and leaned over to kiss the top of his head. Raph’s rumbling churr vibrated through Mikey. Leo grinned and said conspiratorially, “I can find us a private beach.”

“No beach balls,” Donnie said reflexively, and Mikey laughed for the first time all day.

Maybe all he’d needed was his brothers to help him through this. It was nice to think about not being afraid anymore someday.

Chapter Text

“Donnie. Have you ever done it in public?” Leo whispered from behind Donnie’s chair, reaching around to cup his twin’s clothed slit.

Donnie’s typing fingers paused their clacking on the keyboard, and his sex betrayed him by soaking the fabric of his shorts with warm slick.

“By ‘it’ I assume you mean coitus?” His voice was pitched low, and had a slight rasp to it; if asked, he would say it was because he hadn't spoken or had anything to drink in hours, but he would be lying. “Nardo, you are my only sex partner. I assure you that I’ve never had sexual intercourse in public. Why do you ask?”

Leo kissed Donnie’s neck, pressing his warm wet tongue against his scales. “Would you like to try it? We could go to the Hidden City, fuck in plain sight. If we’re careful, no one will even notice, but we’ll know.” Donnie could feel the curve of Leo's smile on his flesh. “We’ll know that if someone looked at just the right moment, they'd see me pushing inside of you. They’d see you make that sexy face when your pussy opens up for my cock. When that delicious feeling hits both of us and we know it's about to get even more amazing.”

Donnie shivered and quickly saved what he’d been working on, then shut down the program. “Yes, ok, you win, Leo. Let's do it!”

Leo grinned. “Get showered and dressed. I’ll meet you here in 15 minutes.” He moved his hand away, but not before giving Donnie a little rub through his shorts.

Donnie watched his twin portal away, and he bit his lip, staring down at himself. 20 minutes was surely enough time to take the edge off, right?

By the time Leo arrived back in the lab in a nice pair of slacks and a light blue dress shirt, Donnie was waiting in a light purple sundress, with the most delicate white panties with a pattern of dark purple violets, and thigh high white socks with cute purple kitten heel shoes.

They portaled to the Hidden City, and then Leo made another portal directly to a resort he’d discovered the last time he’d come here for work. It was adults only, and while it didn't actually happen very often, anyone could indulge in public sex acts here without anything worse than someone staring.

The first thing Leo did was bend Donnie over a table in an outdoor cafe, lifting up the bottom of his dress to prop it up above his tail, and shimmy his panties down so he could eat him out from the back.

“You pregamed, didn't you?” Leo remarked between licks. Donnie's pussy smelled delicious, with lots of fragrant musk and slick that made Leo realize he’d already had an orgasm in the shower. “Or should I say, you pre-came?”

“Ohhh fuck, Nardo!” groaned Donnie, knees already turning to jelly. “Yes, I fingered myself and came with your name on my lips. What did you expect? You can't just–AHHH!--tease me like that!” He shifted so his legs were apart just a little more, and writhed as Leo latched onto his clit and sucked mercilessly.

Several Yokai walked by, not overtly staring but giving them curious glances. Donnie blushed brightly and came suddenly, slick pouring down his thighs and wetting the tops of his socks. Leo lapped it up enthusiastically after Donnie was finished.

“You're into this,” Leo purred against his thigh before moving up to bite his ass cheeks, one bite per cheek. “Is it the humiliation? Or do you just get off on them seeing you with me between your legs?”

Donnie panted and whined, flapping his hands as Leo licked up his crack and covered his tail in tongue kisses. “Both! Oh fuck me, Leonardo! I can't take much more of this!” He looked back over his shoulder at Leo and his pupils dilated, his tongue poking out to see his lips.

Leo pulled back with a grin and wiped the slick from his face with a fancy cloth napkin. “You're a delightful feast, Donatello. May I have the pleasure of being inside of you now?”

Donnie’s eyes and mouth watered with longing. He watched Leo stand up and unfasten his belt, then unzip and drop his pants, revealing no underwear beneath. With a quiet gasp and a grunt, Leo dropped into his hand and gave himself a few quick strokes. He was already dripping precum from the flushed tip.

“Please, do it!” Donnie begged. “I was made for you!”

Leo pushed inside with a loud moan, and Donnie moaned with him. The way Leo’s dick parted his inner walls and opened him up, as well as the friction against his stretched out slit, made Donnie feel like he was on display, even though Leo's body was shielding that part of him from public view. He could imagine Leo felt the same, with Donnie’s most intimate parts squeezing his cock in a wet, hot embrace. Donnie wished he could see Leo’s tail twitching, his sexy ass cheeks flexing as he fucked into his twin.

Donnie had to look away as he saw Leo’s expression, so open and turned on and vulnerable. If he didn't, he was going to cum way too fast. How anyone could ever resist this gorgeous slider, he had no idea.

He met Leo’s thrusts, impaling himself on that luscious cock, and moved his hips in little circles, clenching each time Leo bottomed out.

Leo was letting out chirps and clicks as his self control faded and his turtle brain took over. A steady churr built up and grew louder. He fucked into Donnie faster, and his hand found the softshell's little clit blossom and rubbed.

Donnie’s eyes rolled back and he hissed and groaned shamelessly. He gripped the edges of the table, rattling the silverware and knocking over a water glass, which rolled off onto the patio and shattered. He ground his pelvis against Leo’s fingers and let the waves of pleasure build to a crescendo.

Leo spilled into him, pulses of cum painting his insides. Donnie came with a violent shudder, spraying the hard tile patio floor with squirt and slick. When he finished, he sucked in air with a loud gasp. He hadn't even realized he was holding his breath.

The sound of applause startled them both. Donnie and Leo looked up to see a group of lizard yokai watching with unconcealed interest.

“That was beautiful!” one of the ladies praised them. The others made similar comments of appreciation.

The twins laughed, flustered and embarrassed but preening at the positive attention.

They quickly cleaned themselves up and Leo portaled them back home, directly to the lab. Then they undressed completely, ignoring everything but the burning heat under their scales as they fucked on every available surface. They were insatiable.

Donnie made a mental note to ask for this again on their next birthday.

Chapter Text

Raph's eyes glowed an eerie shade of yellow-green as he wrapped a large hand around Donnie’s throat and lifted him, pressing him against the kitchen wall in front of the whole family. His leg was the only thing supporting the softshell turtle and keeping him from panicking. His grip was loose enough not to constrict blood flow or air, just enough to make Donnie submit to his big brother.

“Raph,” grunted Donnie, “let go. I don't want to fight you.”

Raph ignored Donnie’s pleas and tore off his younger brother’s shorts. Donnie stiffened, cheeks getting hot.

“Please leave,” he said to his family, eyes averted. “I'll be fine. If you leave, maybe he’ll relax and let me go.”

Splinter and April both looked furious, but before they could say anything, Leo opened a portal beneath them and sent them to April's apartment. He and Mikey left on foot, but not without parting words.

“If he comes out of it anytime soon, let us know,” Leo said calmly. “We trust you to figure this out, Dee. Love you both.”

“Be careful!” Mikey spoke up worriedly. “I don't think he’ll hurt you, but I don't want either of you to get hurt if he forgets his own strength!” He sounded like he was about to cry. “I love you!”

Donnie didn't speak out loud, but he fingerspelled ‘I love you’ to them. He glanced over and gave them a soft smile, reassuring. He didn't want them to worry.

Leo gave him one last encouraging smile before pulling Mikey out of the room and portaling them away. Donnie could see the blue flash of his ninpo.

Raph growled, sending a chill down his spine. Donnie looked back at his big brother, forcing himself to make eye contact. Trying to ignore how the hand on his throat and the knee pressed against his cock slit made him want to drop. He reached up slowly to rest his hands on Raph’s chest for a moment, rubbing his pectoral scutes, then moving up to his shoulders. Massaging them, careful not to get scratched by the sharp top edges of his upper plastron.

“Raphala. My biggest brother, my hero, I’m not here to fight you. You can let go of me. I won't run away.” Donnie spoke softly, submissively, lightly stroking Raph’s scales, moving one hand up to cup his cheek. “I want whatever you want. We can hang out or spar or have sex. We can cuddle. We can go soak in the tub if you want to have some water time. Can you let go of my neck, please?”

Raph’s eyes flickered for a moment, the glow fading a bit. His chasm deepened and he loosened his grip, moving his hand away. He used it to touch Donnie’s plastron instead. Donnie’s breath stuttered as Raph’s big rough hand slid down from his chest all the way to his abdomen, holding him below where a human’s navel would be. The pressure caused Donnie to drop with a quiet whimper.

“Ohhhhkay, Raphie, do you want me? I’m all yours if you do.” He let his thighs fall apart, showing how wet he was already, how his long thick purple cock was standing at attention with the tip spread open and glistening. “I am very much consenting and very happy to engage in sexual intercourse with you. Please help yourself, or you can show me what you need me to do.”

Raph’s mouth fell open, tongue lolling out. He dropped with such force that his shorts ripped at the front seam, and he pulled them off impatiently. His giant cock pressed against Donnie’s plastron, oozing and pleasantly warm.

“Oh. Oh Raph, you’re—you’re very, very big. Too big to fit inside of me without some prep. I don't know if you're cognizant enough to understand.” Donnie rubbed Raph's shaft with both hands and thought for a moment. “Do you trust me?”

Raph’s expression softened fractionally. He leaned in and bonked his forehead against Donnie’s. He made a grumbling noise, as if to say ‘Get on with it already!’

Donnie slid closer and held onto Raph with all of his limbs. “Carry me, Big Daddy. Let's go find somewhere more comfortable for this,” he instructed.

Raph grunted and operated on instinct. He supported Donnie's ass with both hands and carried them into Raph’s train car. They ended up on the floor on a pile of pillows and blankets, Raph’s nest. Donnie got on all fours and lifted his ass in the air.

“Don't get inside of me. I want you between my thighs,” Donnie told him, grabbing his arm for a moment and tightening his thighs around it to demonstrate. “Your dick goes here. And we both get to cum. Understand me?” He ground against Raph's forearm and let out a shaky moan, leaving a wet trail along his scales.

Raph understood. He withdrew his arm and slid his needy cock between Donnie’s legs, holding him up long enough to find the right angle. And then he began to glide, slick and precum providing a smoother experience.

“Oh my Stars, Raph!” Donnie cried out, biting his arm so he didn't do anything stupid like try to bite Raph. It felt like nothing he’d ever experienced before. He tried his best to just let Raph fuck his thighs and do the bare minimum, not challenge his dominance even though he’d much rather be moving now, meeting his thrusts and leaving love bites all over Raph’s body. It was so hard to fight what his turtle brain wanted to do.

The bigger turtle picked up the pace. The friction became a little painful for Donnie. He let out a pained chirp, and Raph slowed down instantly.

“It's ok, Raph, I just need some lube,” Donnie reassured him. He fumbled around with one hand until he found the big pump bottle he’d ordered after Raph’s last season. “Here we go.” He pumped out a generous handful and slathered himself and Raph with it. “There, you may continue!”

It was very quick after that. Donnie couldn't hold back anymore and rocked desperately, which made Raph nearly feral. They came together and made a mess of the nest. Then they washed each other in the shower, getting off a couple more times in the process.

They ended up sparring after that, no weapons or clothes, just chasing each other around and taking turns pinning and getting pinned to the floor. At one point Raph won by spreading Donnie’s legs open and eating him out until he was a breathless mess. Donnie countered this by mounting him, well stretched by now, and riding his monster of a dick until they both came and passed out on the mat, barely remembering to separate.

They woke up still covered in drying fluids, the spell broken and Raph's full mental faculties restored.

“What did I do?” Raph asked, fearing the worst.

Donnie pulled him toward the bathroom for another shower. “You asserted your dominance, we fucked, fought, fucked more, then fell asleep. We had a great time! No injuries,” he informed his big brother cheerfully. “We should probably clean up before we tell everyone to come home, but the lair is remarkably undamaged. Great job, Raphala!”

“Are you sure Raph didn't hurt you?” Raph asked while washing his spunk off of Donnie’s ass, making him quiver from overstimulation.

“You took amazing care of me, my dear brother!” Donnie praised, giving him a soft smile. “You are an attentive, devoted lover, even when you’re not in control of yourself.”

Raph smiled back. “That's great to hear. Uh…do you think you’d ever wanna do this when Raph *is* in control?”

Donnie’s starry eyes and quick nod were answer enough.

When questioned later about what happened, they kept things vague. But Mikey made them a cake that night, sneaking it into Donnie’s lab.

“Congratulations Donnie and Raph!” it said in purple and red icing, with a winky emoji underneath.

Chapter Text

“Raph?”

Donnie stopped at the threshold of the bathroom, wearing his pajamas, his lack of mask (and therefore lack of eyebrows) making him look so young to his big brother. He rubbed his eyes, squinting in the low light.

“Oh, uhhh hey Don, go back to sleep buddy! Raph’s just gonna take a quick shower and hit the hay,” Raph said in a rough voice that shook slightly.

“No, Raphael,” Donnie replied slowly, frowning, “I don't think I will. Come here into the light where I can see you.”

Raph, as big as he was, seemed small as he timidly shuffled toward the bathroom, looking down and hugging himself.

Donnie tensed as he saw the bruises forming on Raph’s face and the scratches on his arms and shoulders. His eyes grew shiny and his hands clenched into fists.

“Raphael. Who did this to you, and why didn't you call me immediately? I could have helped you!” Donnie was upset. Angry and heartbroken at the sight of his brave big brother with marks that were unmistakably from someone he cared about, otherwise he never would have let them get that far.

Raph winced as he wiped his eyes and remembered his bruises. He cleared his throat and answered quietly, “It was Tracy. Or whatever his real name is. He was cheating, and he got mad that I caught him.”

“Oh, that bastard!” seethed Donnie. He took his brother’s hand and led him to the medbay so he could treat his wounds, and along the way he tried to calm down. “I promise you, we will deal with him tomorrow. Right now, please let me take care of you.”

On the way to the medbay they ran into Leo, who’d been wide awake and followed immediately when he saw their faces, Donnie’s upset expression and Raph's defeated and bruised one.

The twins cleaned and bandaged the scratches, and got ice packs and medication for the bruising. Then they took Raph to bed, waking Mikey to join them.

Once Raph was asleep in the middle of the turtle pile, the other three had a quiet conversation about how best to handle Raph’s abusive ex-boyfriend. As much as they wanted to be the ones to beat and torture him (psychologically; they weren't *monsters*), they knew it would be best left to their extended family and friends. So Donnie slipped out of Raph's bed and went to his soundproofed lab to call April, who contacted Draxum, Cassandra, and Casey Junior. He left it in their capable hands.

On the way back to Raph’s room he was stopped by Splinter, who’d gotten up to use the bathroom and overheard the brothers’ conversation. Dropping to his knees, Donnie expected a scolding but received a rare Dad hug.

“I have always known that my sons have the strongest loyalty and love in the Hamato clan. You and Raphael have carried so much for so long. You should continue to face the good and the bad together, Donatello.” When Donnie pulled back to stare at his dad in surprise, Splinter only smiled and explained, “Anyone can see that you are good for each other. Also, when you were small children he asked for my blessing to marry you.”

Donnie laughed out loud, then clung to his tiny father and soaked his robe with quiet tears. “How could anyone hurt him?” he lamented. “He’s the best out of all of us.”

Splinter rubbed circles on his carapace through his shirt. “If only the whole world loved Red like you do.”

After a few minutes, Donnie squeezed Splinter and let go, wiping his face with his sleeve. “Good night, Papa.” He paused before standing, and hugged him one more time. “I love you,” he whispered, in case his brothers happened to be listening.

Splinter chuckled indulgently and patted his leg as Donnie got up to leave. “I love you too, Purple. Go give your brothers a hug from Daddy.”

Donnie sighed exaggeratedly, already halfway to Raph’s door. “If I must,” he grumbled.

Leo and Mikey latched onto him sleepily when he returned to bed. He hugged them back fiercely, mumbling, “That was from Dad.” Then he wiggled free so he could give Raph his hug.

Raph’s eyes fluttered open and he hugged back tightly. Donnie’s breath hitched and he closed his eyes, relaxing, pretending to fall asleep. It only took a few minutes for him to actually drift off.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

It took three days for Raph's physical injuries to fade completely. In that time, he was forbidden to leave the lair or do anything more strenuous than giving a brother a piggyback ride.

Donnie didn't mean to be annoying, although he felt like maybe Leo and Mikey were judging him for clinging to Raph so tightly. No one said a word, not even jokingly. He just couldn't shake the suspicion that he would pay for his unusual displays of affection.

It was just that every time he looked at Raph and what Tracy had done, it made him ache deep inside. The only way to fix it was to give his brother all the love and cuddles he deserved, and he could see an immediate difference in the way Raph carried himself. He was starting to feel noticeably better. And if Donnie could avoid having any more of his own embarrassing emotional outbursts, even better.

He knew that Splinter wouldn't think less of him, but he was supposed to be a grown turtle, not some overemotional crybaby who couldn't keep his icky feelings from spilling everywhere and ruining everything.

Ok, maybe Raph wouldn't mind it, but Leo and Mikey would make his life miserable if they witnessed anything more gooey than the cuddlefest that had been going on for days now. And Donnie had a reputation to uphold.

Wait, did he?

Was he overthinking it as usual? Maybe…maybe he didn't have to be so guarded. Maybe his brothers simply approved.

He didn't want them to think badly of him. He didn't think he could handle it after this whole situation.

He found himself approaching them when Raph was busy having tea and meditation time with Splinter. Leo and Mikey had taken over the TV, squished side by side in their dad’s chair, eating sour candy and laughing at cartoons.

Donnie ignored the other seating and sat on the floor in front of the chair, staring at the screen and leaning back against his twin's legs. He didn't know how to start the conversation, but he would figure it out somehow.

“Worm?” Leo offered, extending the bag. Donnie exhaled slowly through his nostrils and took it, fishing out an orange and blue one before returning the bag. He gnawed on the blue half first, and then yelped in surprise as both brothers pulled him up so he was lying across their laps. He stared up at them warily.

“Spill,” Leo said, frowning. “You don't even like sour gummy worms.” Beside him, Mikey looked worried.

Donnie rolled his eyes. “I don't like the shape of them. The flavors are fine, Nardo. I can tolerate the shape if it means being included in Baja Blast cartoon time.” His lips twitched in the ghost of a smile. “This is nice.”

“Donnie.” Mikey's tone was serious. Donnie blinked and–well, fluffernutter sandwiches, Doctor Feelings wasn't quite there, but he was in the house. He let out a deep, audible sigh.

“Do you think Raph likes me?” His voice came out small.

“Of course Raphie likes you!” Mikey blurted out instantly. “You're his favorite!”

“Yeah, mellizo, why would you think otherwise? Whenever you're around he gets a bad case of puppy dog eyes!” Leo added, a gentle smile crinkling his eyes. “From the way you’ve been all over him the past few days, I think if he didn't like you, you’d know it!”

Donnie stimmed restlessly, playing with the gummy worm, stretching and smooshing it. “But is it romantic? Or is he just being Raph, and is he going to just think of me as his adorable little brother forever? I guess that's fine but…” He looked at them with sad eyes. “I really, really love him. I can't watch him get hurt again.”

“Oh. Donnie, baby, he loves you back, twinsie. Trust me!” Leo reassured him with a laugh and a twinkle in his eyes. “Next time you get a chance, tell him! Or, hear me out, kiss him!” He winked. “Raphie would love that.”

“And! Let me know when it happens, and I’ll make something nice for dinner and you two can have a date night!” Mikey was excited now, all worries forgotten.

Donnie felt better now. The uncertainty was practically gone. He had approval from his dad and brothers, and he believed their assessment of Raph’s feelings.

He sat up and hugged his siblings wordlessly, grateful for their sincere support.

They watched cartoons until Splinter came back in and kicked them out of his chair.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Donnie was alone for the first time in days, sitting in the lab working on some coding for SHELLDON. He wanted to be with Raph, but he didn't want to subject him to boredom while he worked.

Sadly, Donnie couldn't even focus on his work. All he could think about was that sweet face, those big strong arms that held him so tight, his favorite voice that made him feel safe as soon as he heard it.

He knew he was being overdramatic, but he was helpless to stop it. He felt like Raph had gone off to war and he was never going to see him again. He felt abandoned. Even though it was Donnie who had shut himself away to get some damn work done.

It was so stupid. Raph was literally in the other room. Why was he so upset? Why was he on the verge of a meltdown because he couldn't be glued to Raph’s side? Why did he feel like something bad was going to happen to his big brother if he wasn't there to protect him?

Oh. Was that it? Yeah, maybe he was overreacting. Or. Maybe it was the trauma. Maybe he was just triggered, and it was seriously fucking with his ability to control his emotions. Great, thanks a lot, PTSD.

Fuck it. He was useless like this. Might as well go get a Raphie hug and maybe something better would come out of this.

He stumbled out of the lab with his vision too blurry to make out anything but colors and vague shapes. He was breathing too fast, but he felt like he couldn't get any air. Right before he reached the voices that sounded so familiar and comforting even if he couldn't make out what they were saying, he tripped over something and landed flat on his face.

“Ouch,” he tried to say, but it came out in a pathetic whine of Raph’s name, because of course he had to do the most embarrassing thing possible in that moment.

“Ohhh, my bad,” he heard someone say, hissing sympathetically (oh, that was Nardo), and then a big blurry red and green shape that looked like everything he ever wanted in a shape came closer and picked him up, sitting on the floor with a thud and shielding him from view.

“Dee, it’s ok buddy, I’m right here. Can ya look at me?” Raph’s kind voice reached him, and suddenly he could breathe again. A large thumb swiped the tears away from his eyes, and Donnie looked up at his Raphie’s face and the buzzing in his bones stopped.

“I missed you,” he said nonsensically. “You're my favorite Raphie.”

Raph’s expression grew tender. “Aww, you're my favorite Donnie!” He smiled shyly. “Raph heard ya earlier. I hope ya don't mind if I do this.” He kissed Donnie reverently.

Donnie’s heart beat so fast that he was afraid it would burst out of his plastron and fly away. He threw his arms around him and kissed back, a dazed smile forming against Raph's lips.

Ok, maybe Raph did love him back. And he knew it was too soon to rush into things. Raph was still hurting and Donnie was still dealing with whatever this was. But they loved each other and that wasn't going to change.

Donnie didn't get any work done all week. He and Raph resumed their former attachment status, only separating for bodily needs. They helped each other, and surprisingly Donnie didn't get tired of the constant physical contact. They had their date night when they could actually appreciate it.

Tracy was locked in an actual dungeon and beaten by three humans, then psychologically tortured by a yokai. He was released a week later and never heard from again.

Chapter Text

Leo giggled, poking Donnie's tail. “Wake up!”

Donnie rubbed his eyes and squirmed, feeling a funny sensation in his abdomen. He sat up and squinted at his twin. “I’m awake.”

Today was a talking day for Donnie. He couldn't always get the words out, especially if it was a Papa Day. Papa liked to take Donnie into his bedroom once a week and spend some special time with him. Usually it would be reading time, learning about human anatomy with clinical terms and diagrams in textbooks they had found in a library dumpster after hours. Eventually it had become a different type of anatomy lessons. Full color glossy magazines with images of humans with their legs spread, with their bodies pressed together, mouths in places Donnie had always considered to be dirty because of their proximity to bodily waste.

Papa had pointed to a woman's vagina and said in a matter of fact tone, “This is what you have. You are part turtle, so it does not look the same. But you have different parts than your brothers. You are unique, Purple.” He had pointed to a man's penis and said, “This is sort of what your brothers have. But it is shy. It only comes out to play when it is needed.”

“Why am I different?” Donnie had asked.

“You were made different so that your Papa and your brothers could have a special little turtle to play with. It doesn't matter if you are a boy. Your Papa likes boys and girls. Your brothers will learn to like you too.” Papa had moved on to a different topic, and Donnie had assumed it was just another lesson, albeit a confusing one.

The next Papa Day, Papa had locked his bedroom door and shown Donnie what he meant by playing with him. After that, Donnie usually didn't talk for at least a day after Papa Days. What was there to talk about? He wasn't allowed to talk about what happened in that room anyway. And his brothers assumed it was just more nerd stuff, so they didn't ask.

Now Leo was handing Donnie his glasses and pulling him toward the bathroom. “C’mon Dee, I have to show you something!”

The doorknob had a lock, so if you were taking a shower or–or defecating, and needed some privacy, you could keep your brothers or your new best friend April from walking in and seeing something they didn't need to see.

Up until now, the lock had seemed like a good thing. A friendly thing.

When Leo locked the bathroom door and turned to Donnie with a big smile, Donnie felt something strange happening to him, something wet between his legs soaking into his pajama bottoms. He looked down and saw that a puddle was forming on the floor by his feet.

Leo’s gaze dropped and he blushed. “Oh sorry Dee, I didn't ask if you had to go first. Don’t worry, I’ll help you get cleaned up!”

Donnie’s face grew hot with shame. He could smell it now. He’d just pissed himself out of nowhere like a little baby. How humiliating.

Even though he was embarrassed, he felt something else too. A tingling between his legs as he realized Leo had watched the whole thing. He pressed a hand between his legs and for a moment he thought he could feel his pulse there.

The wet fabric felt uncomfortable, though, and he wanted to get out of it. So he pulled off his pajamas, feeling exposed in a way he never had before as he tugged down and kicked off his pants.

Leo got a dirty towel and used it to clean up the puddle on the floor. He kicked it aside and took off his clothes. Donnie watched, interested, as Leo stood in front of the toilet and pissed. He’d never actually watched it before, so he hadn't noticed his twin’s extra appendage.

As Leo's stream tapered off, he shook off the last few drops and turned toward Donnie. “See? Dad explained it to me. I got a penis, you got a vagina. And mine fits inside of yours. We’re twins so we're the same size.”

Donnie blinked slowly and put a hand between his legs again, rubbing along the seam of his slit. He kept staring at Leo's little dick and thinking about how it probably wouldn't hurt.

“Let’s get you clean,” Leo said cheerfully. “And maybe after that we can try it if you want. Only if you want.”

Donnie turned on the tap and filled up the bathtub with warm water and a careful capful of unscented bubble bath liquid. He and Leo both got in together.

They'd always taken baths together, and it was never a big deal. What needed to be private stayed private, and they would always help with the difficult to reach areas on their shells.

Now it felt a little like a big deal, especially when Leo took a soft washcloth and reached down between Donnie’s legs to wash him there. Donnie leaned back and spread his legs wider, helping him to get all the folds clean. He shivered as Leo's knuckle brushed something. He tried to remember the diagrams.

“There, all clean,” Leo said softly. “Flip over for me?”

Donnie obeyed thoughtlessly. He felt Leo touch his tail again, lifting it up, and a churr came out of him. Leo kept stroking his tail as he washed Donnie between his cheeks. It made him feel tingly all over, and he wanted more.

Leo stopped much too soon. Donnie made a disappointed noise but rolled back over and offered to help wash Leo in return.

Leo offered himself up shamelessly. As Donnie lathered up a clean washcloth and washed between his legs, Leo made the same churring sound as Donnie, and the softshell could feel him growing through the fabric. He lingered a little longer, enjoying the way Leo responded to his touch. Then he urged him to turn over and gave him the same tail rub as he cleaned his backside.

Donnie watched Leo with amusement. The slider was actually sliding now, rubbing his swollen little dick on the bottom of the tub. Little gasps and grunts burst out of him as he got closer to…something Donnie didn't remember.

Instinctively, Donnie dropped the washcloth and slipped a hand underneath Leo to massage his dick. He was still rubbing his tail, which he knew felt amazing, and he also knew what he was doing with his hand between Leo’s legs had to feel much better than the hard ceramic tub.

Leo tensed up and came with a string of clicks and chirps, and Donnie knew what that meant because he’d watched a bunch of turtle documentaries for fun and also all the less exciting human sex videos Papa had assigned him as homework. He enjoyed making his twin feel good much more than his creepy rat father.

When Leo returned the favor and found that spot at the top of his pussy that made him see stars, Donnie rewarded him with a kiss like he’d seen on TV, sloppy but nice.

It was easy enough to talk Papa into stopping Papa Days now that Leo was involved, and Leo wanted Donnie to himself. Leo threatened to tell April and Raph what Papa had been doing, and Papa went pale and agreed with Leo's demands.

Leo told Raph anyway. Raph made Papa regret everything he’d ever done to Donnie.

Donnie didn't regret having his real first time with Leo. They fit together perfectly.

Chapter Text

Mikey kept his most cheerful grin on his face as they walked home. He made sure not to give away the excruciating pain he was in with every step, and he made it look natural when he climbed up onto Raph’s shell and rode most of the way, giving himself a break.

His feet hurt. Nobody had noticed when they were playing around in the alley by Run of the Mill and Leo pushed Mikey onto what looked like dust.

It was not dust. It was glass ground into a fine powder, and it had worked its way into his soles. He was bleeding but so far no one had gotten a good look at his feet, so if he was lucky he could play it off as an accident (which it *was* but he knew Leo would take it hard if he found out it was because of him) and get some good meds while his big brother helped get all the glass out.

When they got to the lair, Mikey leaned close and whispered to Raph, “Medbay please.”

Raph stopped in his tracks and looked back at Mikey, startled. “Medbay? What's wrong, Mikey? Didja get hurt, Big Man?”

Leo and Donnie stopped too, focused on their baby brother. Donnie scanned him for injuries with his tech gauntlet, then his eyes widened in horror.

“Michael, don't try to walk or put any pressure on your feet. Raph, please hurry to the medbay and place Michael on a bed. Nardo, I need you to prepare yourself. This is not going to be pleasant. He has–urk!--powdered glass embedded in his feet!” Donnie had gone pale and gagged at the thought of the tissue damage and possible infection.

Leo got hit with a wave of adrenaline and he sprinted ahead to get out everything he needed to take care of his poor injured Mikey. He wasn't panicking or anything. No, he was just. Being efficient. Is what Dontron would say. Nerd. Ha.

Oh Pizza Supreme, was this *his* fault?

He did a quick search and found out that simple school glue could be applied to the affected skin and left to dry then peeled off to get out the glass particles. Which was great except what if they went deeper? He was so glad Mikey had hitched a Raphie ride home.

He turned around just in time for his boyfriend to be placed on the bed so gently, you'd never know how rough his brothers could get in a fight. No, when it counted the most, Raph was a guy with a delicate touch. Well. Not Doctor Delicate Touch. That was Miguel’s specialty.

“Thanks, Big Daddy, I’ll take it from here!” Leo tried to sound as positive as he could with a body full of panic and self incrimination. Eugh boy, time to put on his best face and put his patient at ease. “Soooo, Mikester, looks like you got some glass in your feet. How's your pain right now, scale of 1 to 10?”

Mikey winced. “If I’m not movin’ them at all? 7. It feels like it looks. Like someone took a cheese grater to my feet.” He bit his lip and gave Leo his puppiest of eyes. “Can I get something for the pain?”

Leo glanced over at Donnie, who was standing as far away as he could and wringing his hands. “Dee? Can you get an IV set up for our patient? And grab me a basin and a spray bottle of saline. I need to irrigate these wounds.”

Donnie jumped at the chance to be useful. Even if he was bad with needles, he’d practiced recently, both virtually and on real patients, so he could assist if they had any other world ending crises. He inserted an IV port in Mikey’s arm and got him started on some good meds. Then he grabbed the basin and the saline, and also a lollipop for Mikey.

“You're in good hands with Dr. Nardo,” Donnie said to him with a gentle pat on the shoulder. “If there's anything you need beyond his medical skills, please let me know. I can hook you up with the latest technology.” He winked, handing him the lollipop.

Mikey giggled and slowly relaxed as the drugs took effect. He didn't even notice when Leo gave him a local anesthetic to both feet as well. As Leo rinsed a good amount of glass out of the affected areas, Raph and Donnie moved closer and distracted him with a projection of some Jupiter Jim animated shorts and a running commentary.

Leo got most of the glass out of his feet using the saline, and then he gently blotted them dry with a soft sterile towel and applied a layer of glue to the surface, waiting for it to dry. After a few minutes of that, he was able to peel it off and get the rest.

Donnie did another scan and thankfully there was nothing more embedded. Leo applied a disinfectant spray followed by antibacterial cream and clean white bandages to both feet.

“There you go, all done!” Leo said with a smile that was getting more fragile by the moment. “Dee, can you give him a bag of antibiotics? And if you can hack the cameras so we can see exactly what happened?”

“NO!” Mikey protested too loudly. “Don't look! It’s not worth it. Just call Hueso and tell him there’s some dangerous glass in the alley where we were messing around and someone should clean it up.” He broke into a devious grin. “And can I get some pizza too?”

Donnie snatched Leo’s phone away. “And I will make that call, Leon! You may focus on helping our sweet Angelo recuperate!” He smirked. Leo glared at him, but then his expression transformed into something soft and loving when he looked back at Mikey.

“Is there anything *I* can get for you?” he asked a little sadly. “I know I messed up. This was on me.”

Mikey held out his arms. “Come hold me?”

Leo got up on the bed and cradled Mikey in his arms, and when Raph and Donnie were out of the room, he let his guard down. He kissed Mikey's face all over and sighed heavily.

“I’ll be more careful next time, Sunshine,” Leo promised.

“If you really want to make it up to me,” Mikey said slyly, “you can carry me everywhere!”

For the next couple weeks Mikey got piggyback rides everywhere from Leo, even to Run of the Mill, and Leo got so many kisses from him, and words of reassurance that it wasn't his fault and Mikey still loved him.

(Donnie did hack the camera footage, and found out who had dumped the glass there. He totally didn't seek revenge on Mikey’s behalf. No, that he did for the fun of it.)

Chapter Text

“So, when you say you used to eat rats and leaves, was that an exaggeration, or…?” April paused to look up from the cutting board, coarsely chopped carrots and celery nearly finished and ready to add to the simmering pot of chicken soup on the stove.

Casey used his sleeve to push his hair out of his face, dark eyes briefly glancing over at April. “We did. It wasn't only rats and leaves the entire time I was growing up, but after–after the base where we had the greenhouse caved in, it was harder to grow vegetables. Sometimes we found canned food. Dried pasta. Whatever people had stockpiled before things got bad.” He smiled faintly. “When I was 6 maybe? Uncle Mike found all the ingredients and baked me a birthday cake. It was one of the only times I ever had cake until I came here.”

“That's terrible!” Mikey exclaimed from his spot by the stove. “But I am so relieved that I didn't let you have a childhood with no birthday cake!” He added several secret ingredients, which looked to the humans like ordinary herbs and spices, but Mikey claimed they were infused with magic and would make the soup extra delish.

“It wasn't so bad,” Casey murmured, bringing over the fresh green beans he’d washed and broken into smaller pieces for the soup. “I had you, and you had a way of making anything taste good.” He added them to the pot, and then leaned down to kiss Mikey on the mouth. “Mmm, see? Delicious.”

Mikey laughed and hugged Casey around the waist. “I’m sure having you around was inspirational. Even when you were a little kid begging for snacks. Especially then! I bet I had to use my razzmatazz to satisfy your snacking needs.”

“Right behind you!” April announced before dumping her ingredients into the pot and giving it a stir.

“I was actually too busy trying to sneak into Sensei’s training sessions or Uncle Don’s lab, most of the time. I wasn't much of a snacker. But you tried to make me eat more,” conceded Casey. “You told me I was too skinny. I made a deal. Whatever you could get Uncle Don to eat, I would eat too.”

“And how well did that work out?” April smirked, leaning in to peck him on the lips, then doing the same to Mikey.

Casey blushed at the gesture. “I, uh…I started bringing little finger foods to the lab. With chopsticks, of course. Somebody must have had a conversation with Uncle Don about setting a better example for me, because Uncle Mike would send me in with a big plate full of whatever he had that didn't set off his sensory issues, and Uncle Don and I would eat it all while he taught me whatever he thought was useful. Mostly math, coding, weapons maintenance. I got an education, he got social interaction practice, we both ate. It was nice. Some of my fondest memories were afternoons learning how to do updates for SHELLDON, eating what Uncle Mike called mini tacos. I still don't know what was in them, but they were good.”

“Hopefully not rats!” Mikey giggled. “Well, as long as you live here, you'll never have to worry about food shortages.” He added a few more ingredients and put a lid on the pot. “There, that can just simmer for a while. Any suggestions for what we can do in the meantime?” He smiled at his two lovers with half lidded eyes, untying his apron.

“Well, I think you’ve earned some sugar,” purred April, playing with his short curls. She couldn't wait for his hair to grow longer. It suited him. She wondered idly if it would start to grow in other places, too.

Casey wrapped an arm around Mikey and guided him out of the kitchen. April followed, and they peeked into each room to find somewhere quiet for the three of them to hang out and maybe…make out.

Donnie was in the lab working with SHELLDON, the door open slightly but loud dubstep playing. Visitors were welcome but ran the risk of hearing damage if they entered. As comfy as his newly constructed nest/makeout area was, the trio were more in the mood for some peace and quiet.

Splinter and Leo were actually watching telenovelas together on the big projector, so they didn't care to interrupt their bonding time to ask if they could use Leo's room.

Raph was meditating with his stuffies in his room. It was actually adorable.

They ended up in Casey's room in his big bed that was thankfully adjustable for different tastes. Mikey grabbed the remote and set it to extra soft, so when they all lay down on it, it felt like they were floating on a cloud.

They undressed each other lovingly. Lying on top of the blankets, lost in warm kisses and tender caresses, they lost track of time.

Mikey jumped as two large calloused hands spread his round ass cheeks and a warm, wet tongue dragged along his crack and under his tail, then back down to tease his hole. He whimpered and buried his face between April’s breasts, lifting his lower half up off the bed, dropping into her waiting hand. Casey's stubble rubbed against his scales as the man ate him out hungrily, growling in his best approximation of Raph’s churr.

April held Mikey’s carapace with one arm, steadying him as she stroked his throbbing, weeping cock with her other hand with firm pressure and little intermittent twists that caught him off guard. He could only clench his fists in the sheets and take it, moans and chirps and clicks muffled against her soft chest.

She smelled like the two of them, musky but with her own sweet undertones cutting through their scents. She was like fresh baked cookies on a fall afternoon, sweet and still scorching hot from the oven, the salt of her sweat dissolving against Mikey's tongue like buttery shortbread as he desperately kissed and licked her wherever his mouth pressed against her. She sighed shakily and scratched his shell with her sharp little nails. Her other hand was pumping him steadily until he seized up and overflowed, thick white cream coating her fingers.

Casey kissed his quivering hole and withdrew, admiring the beard burn he’d left on Mikey’s scales. He squeezed lube onto his long fingers and began to stretch him open. “I hope you’re ready for me, Michelangelo,” he said in a low, husky tone that made the box turtle tremble. “I can't wait to fuck you. So sexy, so hot inside.”

Mikey was still dropped, still hard and very sensitive but so ready to be inside of April. He gasped when she spread her legs beneath him and guided him toward her slick pussy. “Come on, Mike, I'm ready. Fuck me like you mean it!” she purred.

He slid inside of her and bottomed out fast, churring. His mouth found hers and he kissed her roughly. Behind him Casey withdrew his fingers and slowly sank in.

They fucked in a loud, messy rhythm, lube and slick and saliva and sweat easing the glide of their bodies as they moved, panting and moaning, Casey’s thrusts slapping against Mikey's ass as the force and momentum pushed the turtle deeper into April.

They urged each other on, filthy words gasped out loud like breathy prayers. When they reached their peak, it was a chain reaction of heat and liquid and bodies clenched tightly together, teeth sinking into flesh, claiming each other.

They lay together long enough to catch their breath and enjoy the afterglow. Mikey watched his two favorite humans kissing lazily, and he wondered if they would ever want to make this connection more permanent. A discussion for another day, for sure.

One long, very distracted shower later, they walked into the kitchen together, glowing and affectionate.

Leo stood by the stove, peeking into the bubbling pot of soup, smiling widely. He turned to face the trio.

“Something smells delicious in here!” he remarked, observing. “You all look like you're in a great mood!” He winked. “Cooking something good?”

“You know it!” Mikey grinned, glancing at both of his lovers. “Couldn't have done it without my two lovely assistants!”

Leo laughed, deep affection in his gaze. “I’m happy for all of you!” He rushed forward to pull them into a hug. “Whatever makes you happy! You deserve it!” From the way his breath hitched for a second, Mikey knew that Leo knew, and was giving them his blessing. “Do me a favor. Stick around for a while, ok? Let us see your happy faces.” His tone was quiet and pleading.

“Aww, Lee, we’re not going anywhere!” Mikey exclaimed, hugging him tighter. “We have everything we need right here!”

“Yeah, besides, rent’s expensive!” April scoffed.

“I’m perfectly happy here!” Casey said cheerfully.

At dinner they sat together, not hiding anything from the rest of the family. They got compliments on the soup, and congratulations from everyone.

When Donnie asked super casually when they planned to make him an uncle, Mikey made a mental note to have that relationship discussion sooner.

Chapter Text

Donatello stood in the doorway to the medbay, swaying slightly as his energy still wavered. He’d come straight from his Michelangelo’s bright orange portal and used most of his remaining ninpo to decimate the Krang presence in this timeline with giant sprinklers of all things, filled with the herbicide that melted them. His younger counterpart Donnie had joined him, using his arsenal as a distraction to keep the Krang from noticing Donatello’s presence until it was too late. The other young Hamatos had helped evacuate the city and fight off the hounds and zombies with their own tanks of herbicide and their mystic weapons. Leo had been ready to sacrifice himself to trap Prime in the Prison Dimension when he ran out of Krang melting juice, but Donatello had stopped him with a few crucial words over the comm: “Portal me to you. Trust me.”

Leo'd been grateful for a way out of what would have been a death sentence, or worse. He’d opened a portal under Donatello's feet and the older softshell had stared the ancient, ugly pink bubblegum motherfucker in the eyes and blasted him with a ninpo fire hose full of herbicide that reduced him to a puddle in seconds. Then Donatello had eyed the Technodrome and given it his loudest “FUCK YOU KRANG!!!” before climbing on board and blasting the inside of the ship with herbicide too. Anything made of Krang matter dissolved. The rest…

“I’ll take it from here, Big Dee,” Leo had told him with a gentle pat on his arm. “Let's get out of here.”

They'd left the ship, and Leo had used most of his energy to make thousands of little portals and destroy the Technodrome in pieces. Then Casey had pulled the Key and the Prison Dimension was closed forever.

With one last big portal to the lair, Leo had taken them all back home. Then everything caught up with the slider and he collapsed, and Donatello had carefully lifted this little version of his twin and carried him straight to the medbay, laying him down on a bed. He'd had to sit down immediately after as his own ninpo depletion made him lightheaded. His head between his knees, he’d let his battle shell dissipate and taken the small furry hand that slipped into his own.

“Rest, Purple,” this timeline’s version of his father had said kindly. “You have saved us all. I am so proud of you.”

Donatello had accepted a hug from Raph a moment later, burying his face into the young snapping turtle’s plastron, helpless against the rush of memories that made tears overflow and drip onto the floor. Mikey and April had joined, and a few seconds later he’d felt Donnie’s comforting hand resting on his shoulder, pushing energy into him, recharging his ninpo just enough for him to regain his composure.

“Enough, Donnie,” he’d mumbled against Raph's chest, swatting at Donnie's hand. “Save some for yourself. I may be old but I'm not likely to drop dead if I'm a little tired.”

“Scoff. You don't even realize what you’ve done for us, do you?” Donnie had retorted, voice suspiciously thick. “You saved the world and you saved my twin. We can never repay you for that.”

Donatello had lifted his head and stared at Donnie, his reddened eyes meeting the stubborn gaze in similar condition. “I would do it again and again for all of eternity if it meant you didn't have to live without him. The world was just a means to an end.”

“Hey, Donnies, no need to argue,” Leo had said a little deliriously from his bed. “There's plenty of me to go around! In fact you might both fit up here if you tried really hard!”

“Don't be ridiculous, Nardo,” Donatello had said in a dangerously wobbly voice. “You know I’m too big. Donnie, go be with your twin. I need to use an actual working toilet, and probably shower for at least half an hour.”

“I’ll give ya some clothes,” offered Raph, patting him on the carapace. “They’ll be a little big but Raph’s the only one big enough to share with ya. Any preference?”

At his limit, Donatello had only shook his head and squeezed Raph tighter for a long moment before wiggling his way out of the group hug and heading for the bathroom. After his luxurious shower, he’d emerged wrapped in comfort that smelled like his big brother, feeling less like he would fall apart at a moment’s notice.

Now, he was back at the threshold to the medbay, trying to decide if he should go in. The rest of the family had dispersed to different areas of the lair. He could smell Mikey's cooking, hear the sounds of furniture being moved (that had to be Raph and April) and the unmistakable theme song to one of Splinter's telenovelas.

Leo and Donnie were curled around each other on the bed, kissing tenderly. Both had been crying, but they looked like they’d reached the point where nothing mattered but the fact that they were alive and together.

Donatello's breath stuttered and his eyes overflowed without his permission yet again. His feet carried him forward. Donnie and Leo broke the kiss to look at Donatello, and Leo reached out for him.

“C’mon Big Dee, what's the worst that could happen? We break the bed, and then we have to move to Raph’s room, and suffocate in a pile of teddy bears?” he asked, face soft and worried but faintly amused. “You’re so thin you disappear when you stand sideways. We'll be fiiiine!”

Donatello giggled. It startled all three of them, but it broke the tension. He’d been teetering on the edge, halfway between sobbing and laughter, and apparently Leo’s sense of humor was the best medicine in any timeline.

“Fine, but don't blame me if you're uncomfortable,” he answered. He accepted the offer and climbed up into bed with the twins. They settled with him lying in between them, Donnie and Leo each half on top of him. To his surprise, they both got to work kissing away his salty tears, licking his scales, making him giggle again. Sue him, it tickled!

They took turns kissing him on the lips, pouring love and comfort into him. He let them, kissing back and trying very hard to be grateful for a second chance. It was amazing how everything had gone right, and he’d survived so he could be with these sweet little twins who apparently loved him as unconditionally as they loved each other.

He wished his Leo could be here to meet them. It was his one regret. They'd have loved Leonardo too.

The trio fell asleep, and every time they woke up they kissed again, affirming life and love.

The Hamatos adopted Donatello into their family, giving him a place in the lair, his own room and a work space away from Donnie’s so he could have his independence, but he always ended up sleeping with one or both of the twins. And they always gave him kisses, on his lips or any number of places on his body.

He never felt so loved.

Donatello woke up one morning with a sensation like butterflies on his scales. He opened his eyes to the sight of blue sparks in the air above the bed. Donnie and Leo lay motionless beside him, still sleeping very deeply.

He turned and left soft kisses on their faces, gentle enough not to wake them.

His scales began to ache as the sparks lingered. He got out of bed and took a few steps away from his sleeping lovers.

The sparks fled, almost bashfully, and Donatello watched them gather in a familiar shape, a face.

He didn't need words to know that this was his Leonardo, reaching out to him in the only way he could.

“Leo,” Donatello whispered, eyes shining brightly in the blue glow. “I still love you, always.”

Leonardo formed a heart shape with a strobe effect, an ‘I love you’ just for him. It made him smile through tears, remembering moments when they danced together.

The clock radio jolted to life, soft static turning into a Whitney Houston song, I Will Always Love You. It played from beginning to end, and then it shut off. In the silence, Donatello's quiet sob was deafening.

The twins were wide awake now, having been awakened by the radio, and they sat up in bed staring at the glowing ninpo heart. They watched it slowly fade away, and then Donatello turned and came back to bed, letting them hold him.

It was bittersweet, but Leonardo's message had been crystal clear. Donatello might not like it, but he could appreciate the intention, and he loved these twins just as much as he’d always loved Leonardo. So maybe he’d respect his wishes and do what his twin wanted.

He’d gotten his goodbye kisses, after all.

Chapter Text

Donnie crouched on top of the refrigerator, waiting for the right moment. Mikey had put out a plate of fresh baked chocolate chip cookies in the kitchen. It was only a matter of time.

Raph entered the room within seconds as expected. He approached the counter, looking both ways before slowly extending one big hand to grab a fistful of cookies, intending to cram as many in his mouth as possible then run.

His only warning was a hiss before Donnie landed on his shell, careful to avoid the big spikes, and leaned his head down to bite Raph’s shoulder. Donnie’s fangs cut through his flesh like a hot knife through butter, and the softshell latched on, refusing to let go.

Raph quickly stuffed cookies into his mouth and yelled in pain, crumbs spraying everywhere. He flailed, trying to pry Donnie off unsuccessfully. After he swallowed down the cookies with a big mouthful of milk straight from the jug, he sat down on the floor and leaned back, throwing Donnie off balance and using his weight to crush him into submission. Donnie reluctantly let go and scrambled to get away, claws scratching against the kitchen tiles. When he escaped, he ran out of the room, snatching three cookies on his way out.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Casey Junior was bare ass naked on his bed, fast asleep, face down with his head turned to the side, cheek smooshed against his pillow. Donnie crept into his room and got up on the bed, salivating as he contemplated the feast before him. If he could do it without waking him up, Donnie would lick and suck him all over, leaving hickeys on every inch of his skin. But Casey was a light sleeper and Donnie would be lucky if he could pull this off without the young man startling awake and trying to kill him.

So. Donnie leaned in and sniffed Casey, making an effort not to touch him yet. Mmm, there it was. That delicious masculine scent that made him just a little unhinged. He didn't want to disturb him, but he wanted a little taste.

He quickly grabbed a handful of Casey's ass and bit into one of the fleshy mounds, appreciating the firm muscle underneath but loving the extra layer of fat that he’d developed living in this new (to him) timeline. Perfectly balanced, with a satisfying squish.

Casey tensed and moaned. “Donnie?” he mumbled, eyes barely cracked open.

Donnie released him and licked his lips. “My apologies, Casey. Go back to sleep.”

Casey scrutinized him for a moment. “Finish what you started. This ass won't eat itself.” He lifted up slightly, pushing a pillow underneath and spreading his legs.

Donnie blinked, face heating, caught off guard. Casey wasn't usually this blunt. But if that's what he wanted, who was he to disappoint him?

He adjusted his position, lying plastron down between Casey’s legs, and spread his delicious cheeks to lick along his crack and tongue his puckered hole.

Casey growled, and Donnie could smell his cock leaking precum. He smiled between Casey's legs, and got to work eating him out.

By the time he finished, his jaw was sore and he was achy and wet between his own legs. Casey pinned him down, licking his pussy until he squirted, and then fucking him hard. Donnie fell asleep afterward, satiated.

Casey was just as bitey as Donnie, apparently. Donnie woke up with bite marks on his thighs and a very hungry Casey ready for another round.

This time Donnie sat on his face, and Casey rewarded him by eating out his cunt then his ass.

They soaked in the big bathtub together afterward, both too wobbly to stand in the shower. And when they showed up to watch a movie with the family, everyone pretended not to notice they were both covered in marks.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Donnie was trying to concentrate on some delicate soldering work, and Leo wouldn't stop talking. The slider had invited himself into the lab and sat up on the only bare space on Donnie's workstation (and no, he was not admitting that he left that space clear on purpose), talking nonstop about a comic he’d just read.

“Hey, Dontron, are you even listening?” Leo asked, sounding a little disappointed, and Donnie might be annoyed but he also had a weak spot for his twin. When Leo waved his hand in Donnie’s face, Donnie shut off the soldering iron and set it aside so he could grab Leo’s appendage and inspect it closely.

“What are you doing?” Leo’s tone softened as he seemed to realize he had Donnie's attention.

Donnie took a breath, exhaled slowly against Leo’s palm, then shoved it against his mouth and gave it gentle kitten licks. Leo made a surprised little mewling sound.

Donnie gave his fingers equal attention, kissing and licking them all over, then gently nibbling on them until Leo stared at him with wide, dilated eyes, lips parted like he wanted to be kissed.

The softshell obliged, although he took his time leaving kisses and bites all the way up Leo's arm and shoulder, standing up to reach, then along his neck up to his jaw, and finally kissed his mouth like he meant it. Deep, tender, loving kisses, pausing every few minutes to bite his lips just hard enough to sting, but not enough to leave a mark.

Donnie eventually picked up his twin and held him close on his lap, sitting back down in his chair, just wanting the physical contact. He didn't care about his work now.

When he embraced Leo tightly, breathing deeply with his snout pressed against his throat, Leo made a questioning chirp.

“Dee, are you ok? Not that I'm complaining. It's just that you're not usually this touchy-feely. Should I be worried?”

Donnie’s arms tightened even more, and the softshell’s teeth sank into Leo's shoulder, making the slider groan and dig his claws into Donnie’s scales right above his shell.

“Sorry,” Donnie muttered, giving the bite mark a soothing lick. “I’m feeling possessive. Might be a species typical thing.” He forced himself to loosen his grip, although the action made him whimper at the loss. “You got my attention.”

Leo leaned against him more, rubbing his plastron over his heart. “You can have me. I’m not going anywhere, Dee.” He smiled dreamily. “I don't even mind the biting.”

Donnie smiled back and gave him more biting kisses that turned into lovemaking. They didn't bother moving out of the chair, and he was glad he’d reinforced it so it wouldn't break or tip over given their level of enthusiastic activity.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

April and Donnie ended up on the floor of the comic book store fighting over the last limited edition Red Fox figurine, both trying to reach the box that had slid across the aisle and was just out of reach. Thankfully the store was closed, the cameras disabled, so no one would catch them in the act.

“Get off of me, you sore loser!” April yelled. “I touched it first! It's mine!”

“You dropped it!” hissed Donnie. “Finders keepers, as they say, and losers weepers! And you shall be the weeper in this scenario!” He pinned her arms down while struggling to create a ninpo construct that would grab the collectible and stash it in his battle shell.

April screeched and kneed him in the groin. Donnie was mostly immune to such moves, being a turtle without external genitalia, but her knees were bony and he still had flesh that could bruise. Abandoning his efforts to retrieve the figurine, he retaliated by biting her on the chest through her t-shirt and bra, leaving a dent in her left breast that would definitely be painful for a while. The fabric's texture made him cringe but it was necessary.

April yelped and bit him back, right on his left pectoral scute, and it hurt her teeth but it was worth it for his reaction.

Donnie blushed, pulling away from her and skittering away, staring at her. His shorts had a wet spot right over his pussy, and he was breathing hard. Oh, that was interesting!

April smiled wickedly. “Did you like that, Dee?” she chuckled. “Wow, I'll have to remember that!”

Donnie looked away, embarrassed. “You win. Take Red Fox.” He raised his fist to his mouth and bit his knuckles, trying to suppress the excited turtle noises that wanted to come out.

“Nah, we can share custody,” April decided, crawling over to Donnie to sit next to him. Her hand slid into his shorts and she began fondling him, dipping her fingers into his slick and rubbing him until he gave in and churred loudly.

“April!” he whined.

April responded by fingering him hard and fast until he came, then licking his slick off of her hand while he watched, wide eyed.

“Let's go home,” she suggested with a grin. “I think we got what we came here for.”

The Red Fox figurine sat on top of April's dresser while she and Donnie fucked in her bed, April leaving love bites all over his chest.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Mikey tied Donnie up with his gold ninpo chains, arms bound behind him and legs forced apart, chained to opposite bedposts. He propped up Donnie’s upper half on some pillows and then hovered over him, dropping into his mouth.

Donnie’s lack of a gag reflex made fucking his throat easy, and the softshell knew exactly how to please him, completely hands free. He got off on it too, becoming dazed and compliant, sometimes even having an orgasm from swallowing Mikey’s cum. They'd discussed it in detail before, negotiating what exactly they both wanted out of this. Donnie wanted to be helpless to stop Mikey from using him, and he knew that if it got to be too much and he really wanted to stop him, all he had to do was use a little teeth. Just enough for Mikey to feel it.

Mikey enjoyed the danger, the possibility that Donnie might get too deep into it and forget himself. He doubted Donnie would actually hurt him, but everyone knew that Donnie was a biter. Long before any of them had started a sexual relationship with him, they’d all been victims of Donnie's sharp teeth during everyday tussles. They’d learned to accept that the genius of the family sometimes became a little feral, and that was ok.

Mikey must have been going a little too hard, because suddenly he felt the scrape of enamel against his cock. He froze immediately. Somehow Donnie had controlled the level of tooth pressure. It put the fear of Pizza Supreme into Mikey, but honestly, it didn't hurt. It felt weird more than anything.

Mikey pulled out. “Color?”

“Red. Sorry.” Donnie sounded genuinely apologetic.

Mikey untied him immediately, the chains simply dissipating. Donnie sat up and flexed his arms, and Mikey helped rub feeling back into them.

“What was it?” Mikey murmured, bonking his forehead against Donnie’s comfortingly.

“I thought I’d like that more,” Donnie said in a small voice. “But I didn't like that I couldn't touch you.”

“Oh. Dee, do you need a hug?” Mikey opened his arms, and Donnie fell into them with a grateful sigh, hugging him.

“Sorry I ruined the mood,” Donnie mumbled against his neck. “I don't know what's wrong with me.”

“There's nothing wrong with you. You tried it and you didn't like it. You're allowed to change your mind and need aftercare.” Mikey rubbed his carapace lightly. “Would biting me help? Or me biting you?”

Donnie laughed quietly, a little wetly. Then he hesitantly bit down on Mikey's shoulder.

“You can go harder,” offered Mikey. “I can take it!”

Donnie hummed and bit harder, drawing blood. Mikey moaned and held him tighter.

“That's it, Donnie! You're doing such a good job!” He gasped as the softshell shifted, straddling him and sinking down onto his cock. They held each other and rocked together, finding a rhythm as Donnie unlatched only to bite Mikey in a different spot a few times.

It wasn't their original plan, but they both came and were incredibly satisfied, and Mikey got several bite marks that would last a few days at least. Donnie felt better. They could try again another day, but leave his arms free next time.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

When Donnie found Raph touching his bite marks and, well, touching himself, it was a pleasant surprise. Raph was the only sibling he hadn't had sex with, and Donnie hadn't been sure if his big brother was attracted to him at all. He still wasn't, to be honest. It could just be a biting kink, nothing to do with Donnie himself.

He stepped into Raph's personal space anyway, getting close enough to touch. “Can I help you with that, Raphala?” he asked in a low, seductive tone, staring into his eyes.

Raph growled and pulled him into a biting kiss. Donnie sat on his lap and let Raph fuck his thighs, grinding his clit against the snapping turtle's big cock. They moved together impatiently, chasing their climax.

Breaking the kiss to catch their breath, they didn't bother to hold back their churrs and moans.

“Bite me,” Raph begged. “Raph can't stop thinking about you, ever since the other day when you went feral and bit me!”

Donnie's whole body lit up with flames of desire, and he gave in to the impulse, chomping down everywhere he could reach. Raph reciprocated, leaving trails of burning pleasure with his big sharp teeth.

As they got closer to their release, Donnie made a split second decision and lifted himself up, sinking down onto Raph and letting himself get stretched wide open. The snapping turtle instantly toppled over the edge and filled Donnie’s pussy with a ridiculous amount of hot cum.

Donnie, so full he had to pant to get any air, came explosively, clawing Raph’s biceps as his overstuffed pussy leaked slick and Raph’s cum all over their bodies.

They recovered only to repeat the experience several times. Donnie knew he would be very sore the next day, but he couldn't pass up the opportunity to get fucked and bitten by his behemoth of a brother. There was a reason why Raph’s hugs were the best, and it was his size and his muscles, sure, but it was also the feeling of complete safety and security in his arms. Raph would never hurt him or let anyone else do so.

He could completely let go of all inhibitions and know that he couldn't really hurt Raph, because Raph was so big and sturdy. And his older brother was a big teddy bear, always careful and mindful of his size and strength. Donnie loved the feeling of always being small compared to him, always able to be picked up and held. He would never outgrow him.

And Donnie could take Raph’s enormous dick. He was so proud of himself. He’d had some doubts, but it turned out his flexibility was a feature when it came to sex, too.

Raph wanted Donnie. It wasn't just the biting kink, although they both shared that. They had a very real attraction to each other, and Donnie was glad to know that he would always be welcome in Raph’s arms and in his bed, too.

Now that he knew all of his siblings had similar interests, the wheels started turning in his head. Maybe he could arrange a group activity with everyone. It certainly couldn't hurt to ask.

Chapter Text

Future Donnie (as Leo had cheerfully referred to him when he came out of the portal) cackled loudly at Donnie’s story and patted him on the top of his head with a metal claw. (He was actually going by Othello, but he would gladly accept any nickname these younger Hamatos chose to bestow upon him.)

He put down the soldering iron and took the handkerchief Donnie passed him, wiping the sweat from his face and neck. He’d been working nonstop for the past few hours, assisting Donnie with improvements to the lair. His spouses had insisted, as soon as he’d figured out a power source for his time machine, that he should do penance for his many transgressions against his family and himself, and help make their lives easier, at least for a little while. Of course this was just a bifurcated time branch, but he liked to think he could make a difference with the mundane tasks like repairing the air conditioning and building Mikey a brand new pizza oven. At least this version of his family could catch a break for a week, maybe. He wasn't actually counting the days.

SHELLDON nudged him with his forehead against Othello’s bicep, and passed him a tall glass of chilled flavorless juice and a toasted avocado baco-bagel-rito (with cheese, of course) on a tray, with a duplicate meal for Donnie. Othello took the tray and put it on the card table they’d set up in the garage, then pulled his son into a hug, churring faintly.

“Thank you, SHELLDON! I suppose we should take a break from this non-urgent task. Was this your idea or Michael's?” he asked, smirking down at the ecstatic drone.

“Uncle Mikey would never let me bring you something so deliciously unhealthy, Future Dad!” SHELLDON replied, a synthetic laugh bursting out. “Nah, dude, it's all me! Figured you might not have this stuff where you came from.”

Othello nuzzled SHELLDON’s head affectionately and let him go. “You're not wrong. Avocados went extinct 10 years ago, my time. Tragic sigh.”

He and Donnie picked up their bagel-ritos and ate them, Othello taking his time and not swallowing it whole. Donnie was a bit more impatient, barely chewing it. Othello found himself staring at Donnie, watching his throat muscles work as he swallowed. The older softshell suddenly understood why Leon had always stopped whatever he was doing to watch him eat. It was strangely fascinating and more than a little arousing.

Othello tore his gaze away from Donnie and waved to SHELLDON as the drone left the garage in search of some fun. Then he took a long drink of his juice and casually remarked, “We should go see what Nardo is doing. He hasn't interrupted us in quite some time.” He changed his mask, slipping on the clean one that Donnie had given him, totally missing the heart-eyed look the younger softshell gave him.

Donnie cleared his throat and spoke up a little too loudly in his excitement. “Yes! Let us go rescue my wayward twin from his own dangerous impulses, shall we?”

Othello glanced over and lifted a drawn on eyebrow, but the smile that broke his composure was blindingly beautiful. “Lead the way, my brilliant young Self.”

Donnie couldn't hold back a quiet giggle, which he tried to pass off as an evil chuckle. His hands flapped behind his back and he hurried toward the door. Othello followed, only pausing to adjust the straps of his overalls, which were getting uncomfortable under his battle shell.

Donnie noticed Othello wasn't moving, and turned around inquiringly just in time to see a flash of his older self’s chest before the bib of his overalls was pulled back into place. His mouth hung open for a second before he snapped it shut and wiped his chin in case he’d been drooling. Damn, the old man was fit and had even bigger tits than Donnie had ever dreamed of.

“Come on, you useless bisexual, get moving!” Donnie muttered to himself, and walked with Othello toward the arcade.

Their dear brothers were playing Jupiter Jim vs Lou Jitsu: Space Jitsu, completely absorbed in what they were doing, at least until the Donatellos entered the room and the scent of motor oil and burning metal filled the air. Leo quickly hit pause and jumped up, approaching them.

“Heyyyy, what's going on with my two favorite twinsies?” Leo greeted, walking around the two softshells to check them out. “Mega Don, is that a new mask? It brings out the sparkle in your eyes, really nice look! And Donald, you always look great, no need for anything new.” He winked at them, getting a casually unimpressed look from Donnie and a proud smirk from Othello. Under both expressions he could see genuine appreciation.

“We have been doing upgrades on the Turtle Tank today, and later we will be completing repairs on several small appliances,” reported Othello. He straightened up and winced slightly; his shoulders were starting to get sore from his battle shell.

Donnie noticed, and he leaned in to speak softly. “Would you like to take a break from your battle shell for a few hours? I would be willing to do the same. There are ample charging ports in the lab. If you'd like, I could apply an analgesic cream to ease your discomfort.”

“Oh hey, I can do yours, Donnie!” offered Leo, eager to help. “Both of you probably need it. Also, Big Dee, we do have a Raph sized jacuzzi if you’d like to soak your sore muscles.”

Othello slowly released his battle shell, Donnie doing the same next to him, and they flew off toward the lab to the available docking stations. Othello’s gaze flicked toward Donnie, who was already watching him.

“Would you like to join me for a soak?” Othello asked very quietly. “And Leo, if you're comfortable with him being there…?”

Donnie’s face grew inexplicably red, and he nodded. “That would be acceptable. Nardo?”

Leo’s smile got bigger. “I’m in! Hey Raph, Mike, go on without me.”

Raph and Mikey exchanged knowing grins. “Yeah, sure, have fun!” Raph responded too cheerfully.

“Let us know if you need anything!” Mikey giggled.

The trio headed for the big bathroom, equal parts nervous and excited.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Leo and Donnie undressed quickly, unselfconsciously. They’d been naked in each other's presence many times and it didn't even register as anything unusual anymore. Sure, they appreciated each other's bodies, and even fantasized about each other in the privacy of their own minds and bedrooms. But they’d known each other since they were babies. It was no big deal.

Othello blushed deeply at the sight of them. He averted his eyes, stimming in subtle ways, tapping his fingertips together, taking deliberately slow, deep breaths to regain his composure.

“Are you ok?” Leo queried from his comfy spot in the tub. “You don't have to do this if you're uncomfortable, buddy. It's fine.”

“Does the nudity bother you?” Donnie asked evenly. “If you have become accustomed to wearing clothing, rest assured, you do not have to undress completely.”

“It's…fine,” Othello breathed, unfastening his overalls and letting them drop. He’d already been going barefoot in the lair. He wasn't wearing anything under his main garment, although sometimes he did, if he was planning to go out in public, in case of a wardrobe malfunction. He was safe here, he reminded himself.

He stepped out of the overalls, and heard two quiet gasps. The fronts of his legs were heavily scarred all the way up, and he didn't like to expose them unnecessarily. It was why he liked to wear such an all-encompassing ensemble, so it would be harder for someone to pull down his pants, even as a harmless prank, and reveal his imperfections. He hesitated briefly.

“Hey. Othello? It's ok.” Leo's tone was so gentle, so kind. It left a lump in his throat. “We're not gonna judge anyone here. There's nothing wrong with you. You're so handsome, big guy. Why don't you come in and join us?”

He took a shaky breath, nodding, and met their gaze. He saw nothing but welcoming love in their eyes, and it gave him the courage to pull off his mask and goggles off, and step into the deep, hot water.

Othello’s entire body slumped as the jets hit him all along his carapace and the backs of his legs. He closed his eyes and churred.

“Does that feel better?” Donnie murmured against his tympanum, suddenly closer, straddling his lap.

Othello nodded slightly and wrapped his arms around Donnie, leaning forward to rest his forehead against the smaller softshell's. “This is nice,” he managed to say, nearly inaudible.

Leo moved closer too, leaning against Othello's side. “I don't know how long you can stay, but you're welcome here anytime. Same for anyone else who's back home waiting for you. If, for instance, Other Me wanted to come hang out? You could bring him here. There's plenty of room.” He laughed. “Imagine how much fun two of me would be.*

“He’d like you.” Othello opened his eyes, a smirk appearing. “Fair warning, he’s an amputee, but his prosthetic arm is designed by me, so it's waterproof.”

“You have to bring him!” Donnie exclaimed, pulling back with a manic grin. “I need to see this arm you made! Oh and the Leo it's attached to, of course.”

“Next time,” Othello promised, distracted by the idea of the four of them together in this hot tub.

Leo didn't seem upset at the idea of losing an arm. “He sounds badass!”

“He is,” Othello confirmed, “and so are you.” He moved an arm away from Donnie so he could touch Leo's face, dragging a thumb down one of his stripes. Leo shivered and leaned into the touch.

“My Leo has a scar right here,” Othello told him, pressing a spot right under Leo's eye. “He thought it made him ugly. I told him it makes him look scary, in a good way. No one will ever underestimate him with those striking good looks. In the same way that everything that happened to you makes you more beautiful, Nardo.”

Leo turned his head and kissed Othello's hand. “Same goes for you and Donnie, O.” He studied the older turtle’s face, then pecked the corner of his mouth. Donnie took his cue and kissed him lazily right on the lips.

Othello embraced them both, letting out hungry little growls as he kissed each of them separately, then watched them kiss each other right in front of him.

They were careful not to get too frisky this time, but they were all still wobbly when they got out and dried each other off, having kissed and touched each other with no thought of how long they were in there.

They were barely dressed when they heard a knock on the door. “Everything ok in there?” Mikey called from the other side, and they knew Raph was out there too.

Othello opened the door, feeling giddy. He pulled Mikey and Raph into a hug. “We're fantastic!”

Leo and Donnie followed, joining the group hug.

Othello stayed for two weeks, messaging his spouses every night and filling them in on his budding relationship with the twins. April suggested that she and Leon both tag along next time, and they made tentative plans to come back in a month. And Leon made endless lewd comments about his handyman husband and his big hammer.

When it was time to leave, the twins woke Othello up with amazing sex and gave him lots of goodbye kisses. They knew it was only a temporary separation.

Othello returned to his ravenous husband and wife, and was immediately dragged to the bedroom for round two. He had no complaints.

Chapter Text

Leonardo fell out of the orange portal in the sky, and Donnie just barely reached him in time to catch him mid-air, carefully descending and passing him off to Raph.

The much older version of Donnie’s twin wasn't visibly injured in any way, but Leo still came over to give him a quick check up. Donnie scanned him and the twins examined the results.

“He is unharmed, aside from physical exhaustion and malnutrition,” reported Donnie, “and I believe he is also gravid. Which would partially explain why he fainted upon emerging from the portal.”

“Wait,” Leo frowned, studying the data. “Big Me is pregante?” He turned to his counterpart and carefully tugged down his pants just enough to check out the bulge in his lower plastron. “Wow, not sure how long full term is for a mutant turtle, but he is definitely preganant. Dee, are we looking at an eggpreg or live birth situation?”

Donnie did a more thorough abdominal scan. “I’ll have to get consent for a more invasive ultrasound later, but it appears that he is actually equipped with a mammalian reproductive system and thus is actually pregnant, not gravid. I stand corrected.” He paused, expression neutral but curious. “I wonder who the other biological parent is.”

“More importantly, how did he even get here?!” Mikey exclaimed, looking very nervous. “How many Other Mikeys have to die?!”

Leonardo groaned and covered his face with his hand. “Motherffffather, I feel so gross. Thanks for the save, Donnie. I did not intend to do that.” He peeked through his fingers to see him.

Donnie gave him a gentle pat on the head with his real hand. Raph was now sitting on the ground holding Leonardo across his lap. Mikey held his time traveling big brother's other hand, squeezing it.

The slider’s eyes grew a little shiny. “Wow, look at that. All of you are here, 20 years younger. Hey, Little Me, is my munchkin ok?”

Leo grinned at his older self. “Looks like it, Big Me. Let’s get you back to the medbay and see what else we can find out.”

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

“Wow, first of all, what a cutie!” Leo cooed, looking at the ultrasound image. “How much do you know about them?”

Leonardo took a long look, melting at the sight. “Not much. We didn't have access to the latest medical technology, and Donnie wasn't…around when I found out, so I haven't actually seen them before now.”

“Oh,” Leo said, hushed. “Not to be an insensitive dick, but was he…?”

Leonardo stared for a moment before his eyes widened. “What, the father? No! Not that it wouldn’t have been something out of my childhood fantasies. I always wanted to marry Dee. What a handsome, smart guy, absolutely husband and father material.” He looked a little dreamy, and Donnie tried his hardest to keep his face blank even though he really, really wanted to bounce on his toes and flap and tell everyone how excited that made him.

“But no, it was actually just some guy I slept with,” Leonardo shrugged, looking away. “He was nice, I remember that much. But he also got himself killed on a mission right after, so it's not like he was gonna be any help. And things got really busy and I didn't have time to be slutty so he's literally the only one it could have been.”

“Sorry to hear that,” Leo frowned. “But, I'd be happy to step up and help out with anything you need!”

“Same,” Donnie said in the voice he only used when he was trying to suppress emotions. “Soooo, and feel free not to answer if it's too much, did you and Big Me ever get together in a romantic sense?”

Leonardo laughed a little bitterly. “No, but not through lack of effort on my part. He told me he was too busy trying to win the war to form romantic entanglements. And then one night I caught him with April when he didn't show up for dinner.” He stared down at his hands. “I don't blame him. She was amazing.”

“Oh. That's…I guess good for Big Me, but I don't understand why we wouldn't just form a polycule. It's not like any version of me wouldn't love you,” Donnie mused. “I’m assuming it was a disaster and we didn't ever have the chance to clear things up?”

“I mean, I was pretty upset. Felt like he betrayed me. I froze him out for a while. Then we had to evacuate the base, lost a bunch of people, then the Krang released a biological weapon and he got really sick, never fully recovered. He did his best to keep making weapons and beefing up security but it caught up to him and one day he just didn't wake up.” Leonardo bit his lip. “Can we change the subject? I really just wanna be happy about my baby right now.”

Donnie shrank, looking ashamed, tearing up. “I'm sorry, I-I didn't mean to–” He wiped his eyes and started over. “I didn't intend to bring up bad memories. I just thought maybe we’d have made the most of a horrible situation. But apparently I was a huge dum dum and shut you out and then it was too late and I’m so sorry!” His voice cracked on the last word.

“Hey, no, c’mere,” the big guy responded softly, opening his arms. Donnie climbed up on the exam table and let himself be held. It felt nice, knowing that any Leo in any timeline probably loved him. Even if he didn't deserve it.

“I’m not mad at you, Little Dee. You didn't do it. It’s not *your* fault. I still want to hang out with you and be your friend and, I dunno, your big twin? I know it's weird but we make our own rules all the time, right?” Leonardo rubbed his arm soothingly. “And I don't think Little Lee would mind…?” He glanced at Leo, who was watching them with heart eyes. “Yeah, we're good. Dee, are you ok with it?”

Donnie sniffled and nuzzled Leonardo’s shoulder. “Of course I am, dum dum. Does that mean I get to be an uncle?” He lifted his head, giving him the biggest, shiniest pleading eyes.

“Of course!” Leonardo gasped excitedly. “Are you kidding me? My baby is gonna love you so much!” he beamed.

Donnie hugged him tightly, then let go and got back down from the table. “If you’ll excuse me, I have so much to prepare for! My nibling will have nothing but the best!” He left the medbay, mind racing, but rather than head for the lab, he lingered outside the door, watching the cameras on his tech gauntlet.

Leo wiped off Leonardo’s plastron and helped him sit up. He glanced in the direction of the door. “Do you think he’d be mad if I called dibs on you?”

“Dibs. Really?” Leonardo snorted. “When did I get so popular?” He stood, eyes roaming over Leo's body. “What do you think about the whole polycule idea?”

Leo’s face grew hot. “Nothing against April, but…you and Dee? I wouldn't say no.” He smiled. “You're me with extra steps, and we both know we're hot. And Donnie is gorgeous. I try not to say it out loud because he's always listening and he’ll let it get to his head, but he seemed into you and I really think we shouldn't pass up a chance to get between those thighs.” He sighed. “And we love him.”

“Yeah, we do,” Leonardo smirked. He dipped his head, pulling Leo up onto his toes and kissing him with enthusiasm. The younger slider chirped and kissed back, wrapping his arms around his neck. They explored each other’s mouths, and Leo jumped up and wrapped his legs around Leonardo’s waist.

Leonardo pushed Leo against the wall and his hands moved over his body. Leo reciprocated, churring.

The medbay door opened violently and Donnie came running back in. “Wait, don't start without me!” His face was flushed and there was a bulge in his shorts, and they could smell his arousal. The sliders broke the kiss and Leo said breathlessly, “Lock the door, Donbon.”

Donnie quickly locked it and activated the soundproofing before he approached his Leonardos, pulling off everything except for his mask.

“I am at your disposal. How may I service you?” he purred, leaning against the wall beside them, one hand wrapped around his glistening, swollen dick. He was dripping, his purple petals flexing outward, in search of any contact.

Leo and Leonardo shared a heated glance before Leo hopped down and pulled Donnie in for a deep kiss, his own hand joining Donnie's and his thumb rolling over the tip of the softshell’s cock. Donnie moaned and let go, letting Leo take over stroking him.

Leonardo was curious about his young counterpart’s situation, so he dropped to his knees and carefully tugged Leo’s shorts down, revealing a perfectly juicy pussy just like his own. Oh, no wonder no one had been too surprised by his biology! He ran a finger along the seam, and when he found the smaller slider’s swollen nub, he couldn't help but rub circles on it.

It was Leo's turn to moan, spreading his feet apart slightly so Leonardo could get his large fingers in there more easily.

One finger slid in, then two, pumping inside while Leonardo kept a slow steady rhythm on his clit. Leo continued stroking Donnie’s cock, but also lifted his tail in invitation.

“Do you want to get inside of me, Donnie? I’m soaking wet, and so are you. It wouldn't take much prep,” Leo cajoled, chirping in surprise as Leonardo slid a wet finger into his rear hole, working him open for Donnie. “Oh here we go, Big Me is gonna get me all ready for you.”

Donnie shivered and fought back the urge to fuck Leo’s fist. This was something he’d fantasized about for years, and he wasn't about to ruin it by getting himself off too early. “I want it!” he choked out. “Please, let go or this will be over before it begins!”

Leo released Donnie and held his cheeks open as Leonardo pulled his fingers out of him completely. “Come over here and fuck me then, Donatello. I’m ready for you.”

As Donnie moved forward and pushed inside of his twin with a relieved grunt, Leo leaned over and pressed his face against Leonardo’s round abdomen, moving a hand to the pregnant slider’s pussy and sliding his fingers in. His hand was smaller so it was easy, and he tucked his thumb in after a few thrusts.

Donnie gripped the outer edges of Leo’s plastron near his hips, and his two sliders moaning and the wet sounds of their joining bodies had him reciting the digits of pi in his head to keep from finishing immediately. He focused and used his ninpo to create a replica of his cock so he could stuff Leo’s pussy and fuck him in two holes at once.

Leo whimpered and groaned, trying to fuck himself on Donnie's two dicks, dripping slick down to his knees. To keep himself focused on Leonardo, he started kissing and licking the big slider’s belly bump. He twisted his wrist as he used his whole hand to get Leonardo off, knuckles grazing that spot inside that made his vision white out.

“OH! Oh fuck Leo, don’t stop, I’m gonna cum,” chanted Leonardo, “I’m gonna squirt on your beautiful face!” He steadied himself as Leo picked up the pace, concentrating his efforts on that one spot.

Leo sucked in several shuddering breaths, stuffed full of Donnie, feeling prongs opening and writhing inside as the softshell growled and churred and fucked him mercilessly. He could barely fill his lungs, the exertion and the incredible fullness and the heavenly friction working together to push him over the edge.

Just as Donnie gave in and flooded him with hot cum, sending him rocketing into the sky exploding among the stars, his physical body got drenched by a gush of salty-sweet squirt from his bigger half. Leo was holding his breath, and he barely felt it in his euphoric state, but when he came back down he was soaked and panting and his fist was trapped inside of Leonardo's twitching pussy. He pulled it out as slowly and gently as he could.

The ninpo dick dissolved into nothingness. Donnie was still gripping Leo’s plastron, bent over him, making blissed out softshell noises, somehow still spurting into him for another half a minute.

When Donnie finally withdrew, they all took a few minutes to recover before wandering into the big medbay shower that was designed to hold Raph and an assisting person, so it would definitely hold the three of them. They emerged clean and refreshed, and the medbay had been aired out and sanitized by Donnie’s cleaning bots, so anyone could walk in and wouldn't know anything inappropriate had taken place.

They were, of course, bombarded by curious family and friends when they came out of the medbay. Leonardo announced that he would be staying, and he was coparenting with the twins, to no one's surprise.

The Hamatos weren't stupid. They knew any combination of the twins would always have that freaky connection, and they knew their Leo and Donnie had been pining for each other for years. What was one more Leonardo but an extra element of chaos? And Splinter couldn't wait to have a grandchild!

Six months later, Leonardo gave birth to a healthy half human, half mutant turtle. She opened her eyes immediately, and Splinter cried like a baby when he saw his granddaughter had his eyes.

Cassandra Karai Hamato was going to change the world someday. For now, she was the center of their universe.

Chapter Text

Tella entered the room and made a quick detour to the coffee and donuts table before finding her seat at the big conference table. She balanced her glazed raspberry Bismarck and maple bacon donuts on the lid of her coffee cup, carrying her briefcase in her other hand. Setting everything down, she opened the briefcase and pulled out both a tablet and a legal pad so she could both record the training session and take handwritten notes. She had an entire box of presharpened #2 pencils, purchased for just such an occasion.

She noticed that no other employees had shown up for the mandatory training session included in her new employee orientation, and wondered if she was the only new hire for today. She hoped that she wouldn't be forced to participate in small talk or other pointless activities. Maybe the presentation would be given by a fellow autistic individual, and she would be able to actually enjoy learning about her new job.

She was wearing a dark purple pantsuit with sensible matching flats and a headscarf with longer tails that flowed down her back. She'd grabbed a pair of square framed glasses in a shade of purple that was nearly black, rather than bother with contacts. She wore no jewelry today, except for a cloaking brooch on her lapel that would transform her into a curvy human woman with dark brown skin and almond shaped black eyes if she ever needed to conceal her turtle nature while out and about. It was rose gold, shaped like a violet, and easily activated using a spell that would recognize her mystic signature with a single tap of a finger.

She glanced at the analog clock on the wall. It was nearly time to begin, yet she was the only person in the room. She quickly ate her first donut, being careful not to get any raspberry filling on herself, and washed it down with better than average coffee.

Footsteps clicked into the conference room, dress shoes by the sound of it, followed by the quiet groan of an improperly oiled door as it closed with a final snick. The footsteps continued toward the refreshments, and Tella could hear the melodious sound of coffee being poured into a ceramic mug, followed by the quiet clink of a spoon against the sides of the mug as they stirred in what smelled like white table sugar and a hint of French vanilla flavoring.

“I apologize for my tardiness,” came a familiar voice as Donnie–no, Dr. Hamato–approached the projector screen and set his coffee and plain donuts on the desk at the front of the room. He wore a black suit with an aubergine shirt underneath, and stylish black dress shoes. His mask and tie matched his shirt.

“Dr. Ophelia Von Ryan, welcome to Genius Built Solutions™! I am Dr. Donatello Hamato! It is a pleasure to meet you, and I sincerely hope that you will find this presentation both enlightening and exhilarating!” he said enthusiastically.

Ophelia (she had to start thinking of herself as that persona again for work) readied her tablet to record, and positioned her pencil over the top page of her legal pad, quickly writing the date and subject at the top. She broke into a smile. “The pleasure is mine, Dr. Hamato! I look forward to learning about my new job duties and the company!”

Dr. Hamato beamed and began the presentation, explaining the history and operations of the company in general, then specific information about this branch of Genius Built™ and the role she would have. He showed her maps of the building, including her brand new lab station and the other areas she had access to, as well as emergency exits. Then he showed her images and names of her immediate coworkers, management she would report to, and subordinates who would report to her.

(They took a quick break halfway through the presentation, and spent at least half of that time inside of the unisex single stall restroom with their hands in each other’s pants, making out and getting each other off while holding back their moans. Just as Dr. Hamato was about to cum all over the inside of his black boxer briefs, Ophelia pulled them down and broke the kiss so she could take him down her throat and swallow the evidence. Dr. Hamato returned the favor, helping her up onto the small sink counter and burying his snout in her cunt so he could lick her clean after her quivering orgasm.)

During the second half of his presentation, Dr. Hamato went over security and safety procedures. He explained how to deal with situations such as sexual harassment and conflicts with other employees, and medical emergencies. He told her that while he seldom showed up to work in this actual building, he was available for teleconferences and could be emailed or called if necessary. Sometimes there would be meetings, during which he might appear physically different to protect his identity, and he had taken extra precautions to make sure no one connected the dots about her relation to him or their personal relationship.

After several other minor details were covered, including paperwork she would need to fill out and turn in, the presentation concluded with a Q&A session. Ophelia satisfied her curiosity, both professionally and personally, and after she turned off the video recording app, they made plans for a dinner date on the weekend.

Dr. Hamato gave her directions to his office, should she ever need him while he was onsite, and he escorted Ophelia to her main workstation before leaving her to complete the rest of her training independently.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

After her first day, Ophelia was exhausted. She gathered her briefcase and the rest of the donuts Dr. Hamato had insisted she keep, and headed for the elevator.

Dr. Hamato met her just outside the building, accompanied by Dr. Leonardo Hamato, MD. They were both cloaked, appearing to be human fraternal twins with slightly different skin tones, Leo’s in a brighter shade with vitiligo patterns that mimicked his facial stripes. Ophelia had also activated her brooch before stepping outside, and she missed her resemblance to her counterpart, but she understood the need to distance themselves while in disguise.

The two handsome gentlemen escorted her to her car, and she drove them back to her apartment building. When they got inside the hallway near her door, they all deactivated their brooches and let out a sigh of relief.

Leo pulled a knife out of his pouch and used his ninpo to turn it into a sword. “This is my exit. Dee, are you staying with Tella?”

Donnie flashed him a grin. “I am. Don't wait up for me.”

Leo leaned in and gave him a soft kiss on the cheek, and a forehead bonk. “Have fun, you two!” He pulled Tella’s head down to do the same to her, and then he opened a portal back to the lair and disappeared into it.

Tella unlocked the door and took Donnie’s hand, gently leading him inside. She locked up behind them and put her things away. Then they both headed for her bedroom, undressing, walking into the bathroom naked and taking turns using the toilet and the sink.

Donnie turned on the shower and they both got in. Between kisses, they washed off the grime and sweat of their day. Then they carefully dried off and got into bed, and Donnie got between Tella's legs to lick her pussy until she was soaking wet. She pulled him up until he was sitting on her face, and she licked his cock slit until he dropped straight down her throat. They shifted positions again, and then he was pushing his aching dick into her welcoming cunt, both softshells gasping and moaning loudly now that they didn't have to be quiet anymore.

Tella’s soft thighs (muscled but with a layer of tender flesh on the inner edges that squished slightly against Donnie’s hips) bracketed him, giving him a squeeze like a hug as Donnie rested his face against her bosom and thrust into her rhythmically, slowly. Neither wanted to rush. It felt so nice to take their time making love after a long day being forced to act professional. The quickie in the bathroom had been good but they really wanted to savor each other.

“Donnie,” she breathed, “my love, you make me feel so good, darling. I love you so much.”

Donnie blushed and kissed her pectoral scutes and the soft scales above them. “I love you too, my beautiful Tella. You did amazing today! Such a good girl, so smart and dedicated and perfect. I love the way you feel surrounding me.”

Tella’s eyes sparkled brightly, full of affection and admiration. “You were such a great, patient mentor today! You explained everything so well and made me feel like I belong there. I loved watching and listening to you. You're so brilliant, Donatello.” She rocked her pelvis against him, little clenches around his cock making them both tremble and gush, incredibly aroused. She could feel him flexing and thickening inside.

“Oh Tella!” Donnie twitched, the praise making his head spin, face hot and speed picking up as he climbed toward that peak. “You make me feel so good! Fuck, darling, I'm so close!”

Tella dipped a finger into their combined slick and slid it into the tight opening beneath his tail, working it in. She held onto him tightly with her other arm and gave into her own pleasure, cresting with a deep churr. “Cum inside me, Donnie!”

Donnie cried out, tightening around her finger, and pumped her pussy full of his hot cum. He kissed her chest all over, and found the perfect spot to bite down, leaving a mark.

Tella breathed fast, soaking him in slick as her thighs squeezed him tighter. Her head tilted back against the pillows and she melted. Donnie kissed the mark on her chest soothingly and relaxed on top of her, giving her heart eyes.

Her finger withdrew from him, and she wiped it on the top sheet before massaging his tail very gently. She caressed his carapace with her other hand, meeting his lovey gaze with her own.

His cock softened and retracted, but they stayed together for a long time, cuddling, cherishing each other.

After they separated and cleaned up, they moved to the couch and held each other while watching their favorite science documentaries. It didn't take long for Tella to wonder what it would be like for them to both live here, have their own life together. It seemed like it would be very nice and fulfilling.

She made a mental note to keep Donnie close, and always leave enough space in her life for him, should he ever want to join her. He was a keeper.

Chapter Text

“What is it?” Mikey asked, staring into the big box as Donnie began to pull out the slightly smaller box inside, cushioned by the most inefficient use of brown paper and Styrofoam packing peanuts either of them had ever seen. The softshell used a utility knife to cut the tape on the flaps of that box, and opened it only to reveal…bubble wrap and more tape, apparently, wrapped around a curiously shaped object.

“What?” Donnie said distractedly. “Oh, it's a sex toy, Michael. There were supposed to be two but I don't see the second one–wait, nevermind, there it is. They wrapped them together. Help me free them?”

Mikey helped Donnie find the edge of the tape so they could start unwinding it. Once the tape was off, it was easy to reveal the two sex toys Donnie had been talking about. One was a medium sized dildo with a flared base and a tip that would drip lube as you used it. The other toy was a green scaled fleshlight with a pink and purple liner that looked like what Donnie would have if he had a pussy.

“What do you do with them?” Mikey asked slowly, a little flushed but not at all shy about it.

“Well. I could tell you, but the best way for you to learn is by watching and doing, Michael, so I suppose my answer depends on your comfort level regarding incest,” Donnie stated plainly, blinking. “Are you comfortable participating in a sex act with me, your brother, or would you prefer to watch? Either is fine with me.”

Mikey’s eyes went wide and sparkly, and he took the fleshlight from Donnie to get a closer look. “I don't mind. I wanna try it with you, Dee!” He felt around, pushing a finger inside, humming curiously. “Can we do this one first?”

Donnie’s lips curved upward in a tiny smirk. “Sure we can. One moment.” He locked the lab door and sent a Do Not Disturb message in the group chat, then added a doorknob and a sock emoji in a private message to Leo. He got a thumbs up from everyone, and a winky face emoji from Leo.

“We should be safe now,” Donnie stated. “Before we begin, let's wash these.” He and Mikey went over to the lab sink and carefully cleaned the sex toys. Then Donnie glanced at his little brother.

“Would you prefer to give or receive?” he queried. “I ask because I'm unsure if you've ever masturbated before and I would like to make this a positive experience for you.”

“I, um. I’ve never done any of it before, but I’ve watched videos of humans having sex. And it looks like fun. So, I want you to do things to me. Please.” Mikey sounded nervous but determined.

“I can do that,” Donnie assured him. “Do you need to clean up or use the bathroom before we begin? Things can get messy. And for your first time, I think you deserve to enjoy yourself without a condom.”

“Uhhh I could pee but I’m clean. I just showered earlier.” Mikey shrugged. “Be right back!”

He returned a couple minutes later and undressed. “Where do you want me?”

Donnie led him over to the bed. “Don't worry, there's a mattress protector under the sheets and I just changed everything earlier, so it's all fresh. Make yourself comfortable.”

Mikey got into bed and positioned himself on his back, arranging the pillows to support his hard, round carapace. He watched Donnie undress too, to put them on equal footing. Then the softshell got into bed with him and squirted some lube into his hand, warming it up.

“May I touch your genitals?” Donnie asked hesitantly. “This will go easier if I can stimulate you into dropping and get you comfortable before we introduce the fleshlight. I promise, I washed my hands thoroughly.”

“You can touch me anywhere,” Mikey responded, spreading his legs to give him access. “Just warn me so I expect it.”

“Will do,” Donnie acknowledged, getting his fingers coated uniformly. “First I’m going to touch your slit, rub it with my fingers, and then I’ll put a finger inside and feel around. Let me know if anything hurts or is uncomfortable, for example if I need to use more lube.”

Mikey nodded and watched as Donnie made first contact. His touch was gentle and very light pressure at first, just stroking up and down the seam of his slit with one calloused fingertip. It felt like nothing at first, then warmth and tingling as Donnie kept it going, up, down, back up again, adding a little more pressure with each swipe.

Mikey sucked in his breath and bit his lip. “Donnie. That feels good. Really good.” He watched Donnie’s smile get a little bigger as the softshell added a second finger and just kept rubbing along the edges, up one side and down the other now. Mikey’s slit began to puff up and glisten, not just from the lube. He was starting to leak a little slick, making things more slippery.

“You're doing great, Mikey. If you start to get the urge to drop, go ahead. It’ll feel like you need to push. But I am about to finger you and see if I can get things moving along a little faster.” Donnie met his eyes, took in Mikey's nod, and slowly dipped a finger inside. It lit a flame inside of the box turtle. He could feel a pressure building inside, against his plastron. And then Donnie's finger made contact with the head of his cock.

Mikey shivered and tensed up, the irresistible urge to drop taking over. He pushed against Donnie’s finger, and the softshell chuckled softly, giving him an affectionate stroke before pulling his digit out and giving him room to drop fully. Donnie stared at the impressive amount of slick coating Mikey's erection, and his hand hovered over it.

“I am going to stroke you and get you ready for the fleshlight. You look well lubricated already. I just want to be sure that you're comfortable beforehand.” Donnie wrapped his hand around Mikey’s length and slowly stroked him, squeezing as his fist moved up and down.

Mikey churred and grunted, hips bucking, breaking into a sweat. “Donnie! Please, I need more!” he begged. His breathing stuttered.

“Hey. It’s ok if you cum fast. It's your first time and you'll probably have a fast refractory period,” Donnie told him, leaning in closer, voice soft and breathy. “Just relax and let me take care of you.” He continued jerking him off with a practiced motion.

Mikey felt it a split second before he arched up and spurted cum so hard it nearly made him black out. Donnie continued to talk him through it, praising him until he came down, then making eye contact and licking Mikey's creamy cum off of his hand like it was no big deal. Donnie’s face was flushed, and when Mikey’s gaze flickered downward, he saw the tip of Donnie’s multipronged dick peeking out of the softshell's slit.

“You–you enjoyed that!” Mikey realized, smiling at him. “I thought you were just doing me a favor.”

Donnie licked his lips and winked. “Now you know. I think you're sexy. And I can't wait for you to try this.” He lifted up the fleshlight and added some lube to the inside. Mikey was still hard, and he wanted to try it. He’d never felt anything so amazing in his life.

“Can I try it now?” he pleaded.

Donnie couldn't help but grin. “But of course! Let me help you. I’m going to get you lined up and then I'll do all the work. You just have to lie there and enjoy it.”

Mikey tingled from head to toe, full of excitement and anticipation. When Donnie took him in hand again and rubbed his glans against the opening of the toy, Mikey gushed slick all over the sheets. He was so glad to know that he wasn't going to ruin Donnie’s bed.

“Just relax,” Donnie purred, and then Mikey was inside.

Donnie moved the fleshlight up and down on Mikey's cock, making his toes curl and his face heat up. The box turtle couldn't help thrusting up into it, finding a rhythm. Donnie dropped fully with a quiet moan and began stroking himself slowly with his free hand. His eyes glazed over and he started panting as he stroked both of them.

“Oh Donnie, does that feel good?” Mikey got out between moans and chirps, trying not to get completely lost in his own sensations. Donnie deserved some attention too. “Go ahead, take care of yourself, big bro! You deserve to feel good!”

Donnie actually whimpered at his words, and Mikey pulled him in for a kiss. They rode out the waves of pleasure together, erupting at the same time, shouting and releasing everything.

“Oh my hot cream puff, Michael, how are you so good with words at a time like this?!” Donnie gasped, wiping them both off with a towel and pulling him into a firm pressure hug. “That was so good! You did such a great job!”

Mikey’s smile was wobbly. “Thanks, Dee! I couldn't have asked for a better first time or a better lover! I'm so happy I got to do this with you!”

Donnie bonked his forehead against Mikey's. “It's a pleasure and an honor. Would you like to do this again sometime soon? We still have the other toy to try out.” He grinned mischievously. “If you're too nervous, you can use it on me.”

Mikey grinned back. “I’d love that, Dee. Same time tomorrow?” They shook on it, then spent the next few hours cuddling and making out lazily.

Chapter Text

Donnie and Casey Junior had been gone for hours, maybe not longer than usual for a trip to the Hidden City, but Leo’s intuition was going off and he couldn't relax enough to get into the game of Fish and Ladders he and his other brothers were playing. He exhaled loudly through his nose and half-heartedly tossed the dice. Just as he was about to move his tiny blue plastic fish, he finally heard footsteps coming from the direction of the nearest entrance.

“I don't understand why it had to be me!” Casey complained, waddling into the room with an alarmingly large belly that made Leo think of pregnant people he’d seen in movies. “I’m not the one who pissed off most of Witch Town! Why do I have to be the one who gets punished for it?”

“I told you I'm sorry!” Donnie protested, wringing his hands and looking distraught. “I told them you weren't my partner, but they wouldn't believe me! You were right there! You saw how they just assumed we were a couple and decided it would be fun to make me a teen dad! Well, guess what, Witch Town? I was a dad when I made SHELLDON! I don't need more offspring for that! And I’m not a teenager anymore!”

Leo dropped his fish in shock and felt like his world had been turned upside down. “Wait, what?” he heard himself say from miles away. Maybe he was in a tunnel. His vision was narrowing and he felt nauseous. His Donnie, his twin and life partner, was a father to Casey’s mystic baby? Babies? It looked like it could be multiples. Donnie was a twin so maybe Casey was carrying twin half-softshell babies with Lou Jitsu’s eyes and Casey’s sharp chin and dark hair and–

“Oh shit! Leo!” Raph was swearing; that couldn't be good. Leo’s vision faded to black and he heard his big brother’s comforting rumbling as the snapping turtle caught him and placed him in the recovery position. “It's gonna be ok, Leonardo, we’ll figure it all out.”

When Leo came back to himself, he had a cool cloth on his forehead and Donnie was holding his hand, looking miserable, like he might cry if anything else went wrong. Casey was sitting on a beanbag chair with a hand resting on his belly, guilty and worried.

“I'm sorry Sensei–I mean Leo! I didn't think about how this would look to you. I swear I'm not a homewrecker!” Casey blurted out.

Leo’s heart sank and he reached for his future nephew with his free hand. Casey scooted himself and the chair closer so he could hold it.

“It's not your fault,” Leo whispered. He couldn't make himself talk louder. He was still reeling from the shock. “Stupid witch with a grudge. That's their fault. You didn't do anything wrong.” He glanced at Donnie, who was discreetly wiping his eyes now, and joked weakly, “Does this make me the teen stepdad? Can I be a part of this too?”

He wasn't joking. He couldn't bear the thought of being left out. If Donnie decided doing the right thing meant breaking up with Leo so he could focus on Casey and their offspring, he would probably die of a broken heart.

“Oh Leo! No, please don't cry!” Casey exclaimed, wiping something off of Leo's face. “Of course you’re a part of this! You and Donnie are forever. I'm just the baby mama. Never meant for this to happen, but I’m glad it wasn't with a stranger.” He sniffled. “I guess it means I’m finally a part of this version of the family.”

Leo could actually hear the sound of everyone’s heads turning toward Casey in shock. He sat up quickly, letting go of Donnie and Casey’s hands, and stared through blurry eyes. “Casey. You didn't need to get knocked up to be part of our family. You’ve always been one of us!” He blinked away the residual tears and smiled. “Mikey? I think our Future Boy needs to make an appointment with Doctor Feelings.”

Mikey saluted. “On it! Maybe not today, though. This is a lot. Maybe today we just let ourselves absorb this new information and celebrate! And, uhhh maybe I could call Dad #2 and he could do a mystic exam? Just to check on the latest addition to the family?”

“Draxum? I guess,” huffed Leo. “I’m still mad at him but I’ll allow it.”

Donnie spoke up for the first time since Leo had fainted. “He may be able to determine when Casey is due, and if there are any complications we should be aware of. I may be unprepared, but I would like to know that much.” He placed a hand on Casey's abdomen for a minute, and his eyes widened in surprise. “That was two distinct kicks. Either it’s one very active fetus or we are having twins!”

“Ohhh definitely twins,” groaned Casey. “Doing somersaults on my bladder as we speak. Someone help me up?”

Donnie, feeling very much responsible for Casey's current state, lifted him to his feet. Casey left for the bathroom, and Donnie knelt in front of Leo.

“I realize none of this is fair to you. I apologize for my careless actions that resulted in this delayed outcome. I promise none of this will change my devotion to you, Nardo. I love you just as much as I always have.” He spoke in a gentle tone that was loud enough for everyone to hear. Donnie wanted Leo, but also Raph and Mikey, to know that he was still committed to their relationship. And he hoped Leo wasn't mad at him.

Leo got up onto his knees and wrapped Donnie in a firm hug, kissing the side of his neck. “I love you too, Donbon. It's ok. As long as you’re still mine.”

“Always!” Donnie vowed, hugging back.

Raph and Mikey both applauded, to the twins’ annoyance.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Draxum arrived with very little fanfare, and upon examining Casey in the medbay, announced at first that it was very likely to be a false pregnancy. The twins and Casey all flinched.

“How is that possible?” Donnie demanded, hands clenched into fists. “I might be willing to entertain that possibility, except that multiple individuals have felt the fetuses kicking, strongly I might add! Here, feel for yourself!” He snatched Draxum’s hand and placed it over Casey's abdomen.

The warrior scientist’s eyebrows shot up in surprise. “This should not be possible! However, the evidence is clear. Congratulations on your imminent progeny. I would estimate the arrival to be within a month. Prepare yourself for the unexpected. If you require my assistance, you know how to reach me.” Draxum opened a portal and stepped through.

“Wait!” protested Leo, but Draxum was already gone.

“Great, some help he was!” Casey grumbled.

Splinter patted Casey on the shoulder comfortingly. “He is useless, but we are Hamatos. We will take good care of you. Come, sit with me and have milk and cake while we watch my stories.”

Casey's mood lifted instantly. He followed Splinter to the kitchen for their snack, and then they shared the patriarch’s chair in front of the projector screen, getting lost in the melodrama while indulging in their sugary treat.

Leo fell silent, grabbing a tablet and looking up videos of C-sections in case he needed to perform surgery on Casey. He wasn't sure how that worked with mystic pregnancy in a patient with male-typical sex organs, but he could maybe portal to a Hidden City hospital and sit in on a few procedures. Or they could take him to the hospital there, but since he was a human, Leo wasn't sure how that would work. No, it was safer to prepare for all possibilities.

Donnie pulled up a chair next to Leo and began his own research on how to care for infants with turtle ancestry. He had access to the Hidden City Library’s digital resources, and their collection was impressive. He nudged Leo. “Pause that and hand over the tablet. I can log you into better resources.”

Leo paused his video and peeked over at Donnie’s phone. He perked up as he saw what his twin was looking at. “Oh cool!” He passed the tablet over, and Donnie downloaded an app so he could log into the database and get Leo started.

Raph and Mikey went to the kitchen next to get refreshments. They brought soft drinks and freshly baked non-poisonous pizza puffs to the twins, and found them slumped against each other on one of the beds, sharing the tablet and watching a video about turtle Yokai baby milestones.

“Gimme,” Leo said succinctly, holding out a single grabby hand. Mikey handed him the big plate of pizza puffs, and then once that was safely balanced on his lap, he passed them their drinks.

Donnie was staring at the screen with heart eyes. He glanced up at Raph and Mikey. “Are you ready to be uncles again?”

Raph’s lip wobbled, but he and Mikey were both smiling. “Like a boss!” Raph replied, and he and Mikey high-threed each other.

“You got it!” Mikey cheered.

Leo’s voice trembled. “Dee, we’re gonna be dads!” He put down his drink and moved the pizza puffs so he could hug his twin.

Donnie hugged him back, pressing his forehead against Leo's. “Yeah, we are. And we're the best dads! I think Casey chose ‘Mom’ as his designation…?”

“Whatever, we're parents! Finally living the dream!” Leo laughed wetly. “I hope they look more like you. No offense to Casey.”

“Well, I did inherit the best looks in the family,” preened Donnie, winking.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

In the end, it didn't take long for the babies to arrive, and they didn't need to do any surgery. Casey waddled into the kitchen for breakfast a week later, sneezed, and half a second later two perfect softshell babies appeared in his arms, clean and already wearing diapers. It was painless and the infants were quiet and curious.

The whole family took turns holding them. Leo determined they were a boy and a girl. Draxum pronounced them mystically healthy and recommended training when they were older, but in the meantime suggested that they be treated like regular babies. Splinter got out the book of artists he’d found his sons’ names in, and Casey and Donnie decided to name them Vincent and Georgia. (Leo had half a dozen nicknames for each of them already.)

The next time they went to the Hidden City, Donnie and Casey brought Leo and the twins, and the rest of the family followed at a distance.

The witch who’d cursed Casey congratulated them, and apologized for the deception. They explained that they were a fertility witch, and they'd used them to practice their craft, figuring they could right a wrong against Witch Town and grant a wish at the same time.

Casey gave Donnie a sharp look. Donnie reddened and knelt in front of the stroller, avoiding anyone’s eyes, just watching his babies sleep. He explained after a moment.

“I wouldn't have wanted you to have children against your will, Casey. I did want children, however. I always have. I won't apologize for wanting them.” He stood up suddenly, face frozen in a blank expression. “Excuse me.” He left the stroller with Leo and Casey, walking away in a random direction.

Raph followed discreetly. He found Donnie leaning against a wall in a deserted alley, silent tears streaming down his face, looking lost.

Raph pulled him into a hug. Donnie went limp against him.

“Raphael, am I a bad person if I’m not mad at them for doing this?” he asked, muffled against Raph's plastron. “I didn't think I could have kids. Not without doing what Draxum did. I don't think Casey wanted it. I…I think he resents me.”

Raph churred comfortingly. “Raph thinks ya might be overthinkin’ this. Casey's mad at them. Not you. Casey loves those cute little babies. In a perfect world you and Leo would’ve had ‘em together. But life's not perfect. Maybe the way it happened wasn't ideal. But it did happen and it's nothin’ to be ashamed of. Donnie, it’s ok to love those babies. And it's ok to kinda love Casey too.” He gave Donnie a squeeze. “Families come in all shapes and sizes.”

Donnie sighed and sniffled. “I want to go home,” he pleaded. “Can you take me home?”

“I gotcha,” Raph replied, picking him up and letting him sit on his shell. “Let's go find a portal.”

Donnie texted Casey and Leo right before they went through the portal that led to the alley near Run of the Mill, telling them that he and Raph were on their way home. When they got to the lair, Raph took Donnie into his own big bed and they cuddled until the softshell fell asleep.

He woke up to quiet voices.

“I didn't mean to make him feel bad about it,” Casey said sadly. “I don't regret it. I was just surprised. He really thinks I resent him?”

“You know Donnie. He overthinks everything. He probably thinks I’d be mad if he had feelings for you. Which I think he does.” Leo sounded almost amused. “For an emotionally unavailable bad boy, he has the most feelings out of anyone I’ve ever known.”

“I know exactly what you mean,” Casey mumbled. “He was the same way in my timeline. He pretended he was above all of that mushy stuff but he always made sure I knew how much he cared.” He sighed. “I think I know how to fix this. Move over, Raph.”

The bed shifted and then Casey said a little more loudly, “Rise and shine, Donnie!” Then warm lips made contact with his.

Donnie’s eyes flew open and he instinctively kissed back before his brain came back online. When they broke apart, Casey was smiling.

“I knew you were awake. C’mon. Vinnie and Georgie missed you. I missed you too. We can all talk about everything while we give them a bath,” Casey coaxed, pulling him up out of bed.

In the hour it took to bathe the baby twins (they loved water as much as Donnie did), they negotiated their relationship, with Donnie and Casey deciding on a QPR and Leo and Casey keeping things more brotherly. Not much changed, but everything changed, and most importantly, everyone was happy.

Chapter Text

The Hamatos hadn't seen Don for a few days. The time traveler had left a note in the kitchen with a giant white poster board covered in hand doodled Genius Built™ logos and a giant purple arrow pointing to the note on the kitchen counter. And next to the note itself was a basket full of candy and snacks. Probably to get their attention.

The note read as follows:

Greetings, siblings and Father–

I am going on a quick weekend trip and will be unreachable at this time. I will contact you if I am running late. Rest assured, I will return with gifts for everyone. I apologize for the short notice. Please enjoy the snacks provided in the basket.

Also, Donnie and Leon, I have left you some educational videos. They are in the usual folder on my desktop computer. You know the password.

I love you all 💜

Don

It wasn't exactly suspicious, but for them to leave without a verbal goodbye, no hugs, no chance for any of them to ask to join them? It rubbed them all the wrong way. But Don was the adultiest adult out of all of them. They were free to live their life and to have secrets.

Donnie would have respected his partner’s need for secrecy and privacy if he and Leon hadn't both woken up in a cold sweat the next morning, with the phantom memory of pain and the sensation of trying to push out something that didn't belong.

Donnie activated Don’s tracker. He found them in a location he didn't recognize, but Leon did. It was a cottage on an island Leon escaped to sometimes when he and a brother were fighting, somewhere only really accessible by portal, and the sand was fine textured and pristine, untouched by humans. The water was warm and clear. Leon liked it because he could escape all the chaos and tension and noise of the lair and just exist in peace.

Don was in pain. Don had wanted solitude. They'd known exactly where Leon’s secret island was located. Maybe their Leo had told them, even taken them there before, in their universe.

The wheels began turning in Leon’s head. He thought about softshell turtle instincts, about how Don lived the past couple decades in an apocalypse, and despite all the trust they had in their new family, they might have needed the safety and security of a remote location to lay eggs and not get interrupted by well-meaning individuals like Raph or Mikey.

“Eggs,” Leon said quietly. “They're laying eggs. I think they're having a hard time with it. Can you get our emergency bags? We're going to help Don.”

Donnie nodded sharply and gathered the duffel bags they kept in a safe location in the lab, filled with emergency supplies and their typical overnight bag stuff. He brought them to Leon, and the slider added some comfort items for Don. Texting the group chat with their intentions but not the location, Leon opened a portal straight to the island and they went through.

They stepped into the cottage (unlocked, because who was going to find any of them here?) and headed for the bathroom first. It was a mess of medication bottles, dirty towels, and the unmistakable scent of slick tinged with blood. Thankfully there was running water and all the basic amenities here.

Donnie gathered up the dirty towels to put them in the washer, and Leon moved on to the bedroom. He found Don naked on the floor in a nest of blankets and pillows, with fresh towels under them, already soaked with various fluids. There were two shiny and small eggs in a little portable incubator next to Don, a heat lamp keeping them warm. Don’s face was flushed and damp with sweat and tears, their eyes squeezed shut and face scrunched up with pain and exertion.

“Gah! Get out already!” they yelled in frustration, sucking in great big gasps of air. Their eyes snapped open and widened when they saw Leon there.

“Oh shit! Did I lose track of time?” Don asked wearily. “What day is it?”

Leon got down on his knees and cupped their face in both of his hands. “No, no, you're good. It's only been like a day. But you were projecting your pain onto me and Donnie and we came here to help.” He wiped the tears away with his thumbs. “There's one stuck in there, right? So, I have some ideas, and tell me what you think about them.”

Don blinked and winced as another wave of contractions hit. They curled over their abdomen with a groan and held their breath, straining as they tried to push it out.

Donnie came into the room just as Leon was explaining his ideas. He moved over by Don’s side and held their hand.

“First of all, you need to breathe. I know you're gonna want to hold your breath, but you need oxygen. It's gonna help you. It's just the three of us here and no one's judging you. Breathe.” Leon coached Don through their breathing as though they were in labor. It made them relax more. They remembered what it felt like to give birth to Casey's egg. This was an echo of that.

“You're doing so well, my love,” Donnie praised them softly, kissing their neck. Don whined at the sweet words and pulled Donnie closer, needing more contact. Donnie snuggled closer, wrapping his other arm around them.

“Next thing, maybe Dontron can help you with it. Can you try to drop for me?” Leon asked, leaning in to kiss Don’s forehead. “Your big beautiful dick is making your insides more crowded. If you let it out, Donnie can play with it. And that poor egg will have a little more room to squeeze out. Does that sound good to you?”

Don’s breaths came out shaky, and they stared into Leon's eyes with gratitude and love. “Yes. Ok.” They squeezed Donnie’s hand before letting go, and the younger softshell began to rub along their slit, using the moisture there to help ease the discomfort.

Don dropped into his hand with a little whimper. Then they let out a sigh of relief as something shifted inside. “That…helped. Some.”

Donnie slowly stroked them from the base to the flared tip, thumb massaging their sensitive glans and making them close in, trying to trap the digit like a hungry Venus flytrap. Slick and precum flowed steadily downward. Don’s eyes grew far away and heavy lidded.

“Good boy,” Donnie whispered, continuing his motions.

“Don? I’m gonna get down there and try to help you get that egg out with my fingers,” Leo murmured, moving to lay on his plastron and kiss their inner thighs. He got his fingers soaking wet and pushed one inside of Don’s pretty pussy.

“I can feel it. Next contraction, give it all you’ve got, baby. Donnie? See if you can get them to cum. That might help too,” mused Leon.

Donnie moved his hand a little faster, nibbling on Don’s shoulder and neck as he stroked and squeezed upward. Don was biting their lip and letting out deep moans now.

Leon put a second finger inside and began pressing on their inner walls, finding the spongy nerve center and concentrating on that. Don tensed abruptly and squeezed Leon’s arm between their strong thighs. They came with a shout and a string of turtle sounds, squirting and ejaculating all over their partners’ hands. And a few seconds later, the troublesome egg slid out, pushing out Leon's fingers and landing in his open palm.

“Fucking finally!” Don wheezed. They relaxed completely into Donnie’s embrace, watching Leon clean the egg and place it in the incubator with the others.

“Any more?” Leon wondered.

“Yes, there should be a few more,” Don shrugged, “but they should be easy. There was only one big one. I did an ultrasound yesterday.”

“Wait, here or at home before you left?” Leon nearly demanded. “What do you have here?!”

Don looked a little nervous. “Here. I maaaay have prestocked this cottage with some portable medical equipment before I arrived with Draxum's assistance rather than trouble you with transportation duties and the burden of feeling responsible for my well-being during this ridiculous aka embarrassing time in a turtle’s life. I did not intend for either of you to have to see this.” They looked away, biting their lip. “It seems I was foolish to do so.”

As they were preparing to be scolded by their young mates, three smaller eggs quickly slid out back to back into Leon’s quick hands. In less than a minute they were in the incubator with the others.

“I understand your need for privacy. In the future, please notify us discreetly. We can make arrangements without involving our more rambunctious or stubborn family members,” Donnie requested, giving Don a quick kiss. “Right, Nardo?”

“Exactly!” Leon confirmed, moving closer to give Don a kiss as well. “I’d be happy to portal you and anything you wanted here without you having to involve Draxum. Just let us know.”

Don nodded slightly, relaxing completely now that they were finished laying their eggs. “I will, I promise. Will you help me clean up now? I’m not sure if I can get up by myself after everything.” They smirked. “You made that so much better than I could have on my own.”

“Of course!” both twins said simultaneously. They got Don to their feet and helped him into the bathroom, where they ran them a soothing bath and helped them get in.

“Be right back,” Donnie told them affectionately. He gave them a loving forehead bonk before leaving to take care of the laundry.

Leon stripped and got into the tub with them, and he helped them get washed and get comfortable. When Donnie returned, Leon was lying on top of Don, plastron to plastron, both turtles churring.

“Cute,” Donnie grinned, and he took a picture before getting undressed and squeezing in with them. Somehow they made it work.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The trio left the eggs in the incubator (after a quick check, they couldn't tell yet if any eggs except for the large one were fertilized, so they would deal with that later) and put on their beach clothes and packed a picnic basket with food from the fridge. Cold chicken sandwiches, fruit, macaroni salad, Mikey’s homemade chocolate chip cookies, and water bottles filled with lemonade and iced tea. The basket was insulated and stuffed with cold packs from the freezer, so the food would stay cold for a while.

They put down a huge blanket to lie on and a canopy for some shade when they weren't basking. Donnie was wearing his purple board shorts and a Hawaiian shirt. Don had opted to wear a lavender bikini, wanting as little clothing as possible after the sensory hell of egg laying. Leon had opted to go topless and only wore the skimpiest dark blue booty shorts. He had swim goggles for if he wanted to go into the water, but they stayed off for now.

Don couldn't resist the allure of the water. They left the safety of the canopy and ran for the ocean, practically diving in. They made excited turtle noises, chirps and clicks, and a second later Donnie was running after them, leaving his shirt behind on the blanket. Leon gave in, putting on his goggles and joining them. They swam and enjoyed the marine life, and chased each other playfully until they had to surface briefly for air. They only left the water when they were starting to get hungry.

They took a few minutes to dry off, lying on towels in the sun, sipping their ice cold drinks. Then they went under the canopy and ate their lunch, and took a nap curled up in a turtle pile.

When Don woke up, they had a strong need to affirm their appreciation for their partners, and their bikini bottoms were soaked with slick. They moved away from Donnie and Leon long enough to undress, then slipped a hand into each of their shorts and played with their slits until they dropped. The twins woke up to a naked, very horny Don giving them handjobs and smelling delicious.

Don ended up straddling Leon’s lap, riding his cock while Donnie took their ass from behind and reached around to finger their cock slit, not letting them drop. They moaned and screamed and whimpered as they were filled with cocks and fingers, their nerves singing with pleasure, not enough and too much at the same time. They were covered in kisses and love bites, too lost in the sensations to do anything but submit and chase their orgasm.

Donnie growled against Don's neck and withdrew his fingers from their slit. Don immediately dropped with a chirp, and Donnie whispered filthy words as he jerked them off fast and hard. Don shook apart and came in fountains from their cock and pussy. Leon’s hips came up off the blanket as he slammed up into them and filled them up, and Donnie came a second later.

They continued to touch each other and fuck until they were all too overstimulated to continue. Packing up everything and shoving it through a portal was easy. The trio spent the night at the cottage, and returned home the next day with the eggs and big bags full of gifts for the family.

Only one of the eggs was viable, and it turned out to be Donnie’s child. Don ate the rest at Leon’s insistence. He claimed it would replenish nutrients they’d lost in the whole process of growing the eggs. Don did feel better afterward.

Next time they would all go together.

(When their baby hatched, they were just like Don. A tiny intersex child with a big forehead and curious eyes stared up at their parents and wiggled their fingers and toes. They had the same heart shaped marking on their carapace, only bigger. Absolutely perfect.)

Chapter Text

Donnie woke up feeling like his whole body was on fire. He felt itchy and uncomfortable all over. He was drenched in sweat, his innermost muscles tense, slick forming a puddle between his legs to the point where he felt like he needed to put on the period underwear he’d purchased to wear during his heat.

Oh no. He’d lost track of time, and it was late spring, when the birds and the bees populated the planet and good little turtles kept to themselves so they wouldn't be tempted to fuck their handsome red-eared slider twin who had such a flirtatious manner and a beautiful smile that always made Donnie a little weak in the knees.

He showered first thing, giving in to the urge to rub one out under the hot water while imagining Leo on his knees licking and sucking on his cunt, playing with his tail and fingering his ass until he came, eating him out.

Sweet cinnamon buns, Donnie was feeling like a girl today. A he/him girl, to be exact. He wanted to hear Leo call him a good girl, a pretty girl, a cock slut with tasty thighs. He wanted Leo to bite his thighs all over, dig his claws into his ass cheeks, devour him like a feast. And then he wanted to get bent over and spanked, and fucked hard until he let go in a pretty spray all over, girl cum and pheromones perfuming the air and his tight cunt squeezing Leo’s big dick until it spurted and filled his insides.

Donnie wanted filthy sex with his twin brother, and he wanted it now.

He came with a mewling cry and sank to his knees, fingers buried in his twitching pussy to the third knuckle, forehead pressed against the wall as he rode out his earth-shattering orgasm. And then he used the handheld shower head on his clit to cum again.

By the time he was done, the whole bathroom stank of sex and he was so glad he’d done this in his private bathroom that he never, ever let his family use. Although now he was seriously considering pulling Nardo in there and letting him take a strong whiff before begging him to take him then and there.

It was probably a good thing that Donnie was so skilled at concealing his true thoughts and feelings under an impenetrable mask, right? He was so, so good at lying. Yes. Of course he was…n't.

Damn.

He couldn't get away with being around his family in his current state. So he did the next best thing.

He messaged Leo, something generic like “Meet me in my room as soon as possible. I have to show you something. It's important.” There. Nailed it.

The slider would be so excited to be included, he wouldn't even question it. He’d probably barge in talking nonstop, get a good lungful of Donnie's enticing eau de pussy, and let the softshell do anything he wanted.

His phone dinged. Donnie checked his messages, and gasped in dismay.

“Can't right now, Dontron. Watching a super important rare screening of a Jupiter Jim cartoon short. If you want to come join, hurry up. In my room.”

Donnie wanted to scream. He knew Leo didn't understand the urgency of this whole situation, but he couldn't wait until Leo was done! He would die!

“OMW,” he typed, and ran to Leo's room.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

He didn't know how he'd gotten here. One minute Leo was watching this never before seen Jupiter Jim animated short, only available through a link that would expire in a few hours, not able to be downloaded, couldn't be missed. And then Donnie was standing in his doorway on trembling legs, wearing his special purple undies he only wore during his heat, big pleading eyes filled with tears making Leo weak. The slider could smell him from across the room. He wanted to pull him into bed and eat him alive and fuck him senseless.

But he couldn't.

Fuck, what was he going to do? The solution presented itself.

“Come over here, Donnie baby,” he’d said softly, setting up his laptop on the bedside table. “You can come sit on my dick and sit very still until this is over. And then I’ll take good care of you.” He’d pulled his shorts off quickly and dropped almost instantly from Donnie's scent alone. And then the softshell had come running and straddled his lap facing him, sinking that fever warm, soaking wet velvet pussy down onto his length, and rested his head on Leo's shoulder. And just held on, panting quietly, dripping tears and saliva onto him unapologetically.

Leo couldn't be mad. His poor twin couldn't help it.

The JJ short was starting to seem less and less important when Leo was faced with the reality of a hot, needy little softshell in heat sitting on his dick and dripping with want.

He rubbed Donnie’s carapace slowly, feeling his twin shiver in response, hearing him choke back a whimper.

“Shhhh, you’re such a good girl, Donnie. You're doing so well. Not much longer, baby,” he promised.

Donnie had to let go of Leo to flap his hands excitedly, a big smile pressed against his neck. Leo knew him so well! It made him feel so euphoric to be called Leo's good girl! He kissed Leo’s scales and hugged him tightly, wanting to show his appreciation and love.

Leo hugged him back and chuckled. “You like that, being my good girl? So sweet and pretty.”

“Yes!” Donnie cheered. “I’m all yours!”

“Almost time, Donbon,” Leo purred.

As the animated short finished and the ending credits popped on the screen, Leo pushed Donnie away just enough so he could tilt his head up and kiss him. Even though they were close to the same height, Donnie had deteriorated into shrimp posture. It made him seem smaller. More feminine.

“You were so good for me,” Leo praised. “I’m gonna fuck you so good, baby.” He repositioned them so Donnie was lying on his back, and Leo hovered over him, holding his legs up so he could go deeper.

Donnie let out a quivering moan, wrapping both legs around his twin so Leo could support himself with his arms. Leo kissed all over his face and pulled out almost all the way, then began to thrust into him steadily at a quick pace.

Finally! The slide of Leo's solid cock rubbing against Donnie’s insides felt like relief and soothing heat that built with each stroke. His tail thumped against the mattress and Donnie dug his teeth into his twin’s muscular shoulder, not really biting hard but gnawing on him, wanting to get closer to him.

Leo groaned and went faster, heaping praise on him, calling him baby girl, telling him what a sweet cunt he had, how he couldn't wait to cum inside of his soaking wet pussy so he could eat him out, mark him all over, claim his gorgeous twin as his own.

Donnie came with the most embarrassing noises of ecstasy, hiccuping and squealing and chirping. His scent flooded Leo’s nostrils and set off the slider’s release very quickly.

As soon as he could move, Leo pulled out and got his face down between Donnie’s thighs so he could bite him all over and lick up the overpoweringly good smelling slick that was forming a huge puddle underneath him. He knew that when he was in his right mind, Donnie would be revolted at the thought of touching so many fluids, but right now the softshell was deliberately flaunting how wet he was, not even trying to clean himself up. His hormone addled brain wanted Leo to do the job with his tongue. And that was really fucking hot.

Leo lifted Donnie’s cute ass and placed a pillow under it. He started at the top of his pussy, right where his pubic mons started to split into two puffy outer lips, using his thumbs to spread them open so he could get at the juicy inner labia. His tongue swiped over them, making Donnie churr loudly and tense up, seemingly on the verge of another climax just from the intimacy of Leo’s hot breath and obvious enjoyment of the task before him.

“More more more more more, *please* Leo!” babbled Donnie, undulating. Leo rewarded him with a thumb rubbing circles over his clit and a deep plunge into his weeping hole, swirling his tongue inside and drinking everything he could give. And a moment later he had his other hand wrapped around Donnie’s tail. He kept stroking it and teasing his cute little asshole.

It felt like Donnie was soaring above the clouds, the wind blowing away anything that wasn't Leo and Donnie, exhilaration making the softshell's heart race. He was experiencing a series of orgasms one after the other with very little time in between, his heat making every sensation magnified and his usual intolerance of so much touching shoved aside by his body's biological need to fuck and make little turtle babies.

His thighs clamped down on the sides of Leo's head and he could hear muffled chirping from his twin as arousal fought with survival. For a long moment he could feel nothing but his muscles spasming and white hot pleasure as his cum squirted out like a fire hose.

Donnie’s legs relaxed and fell away from Leo's head, and Leo was just glistening and dripping all over, mouth breathing and face slack. Beautiful, so fucking gorgeous, and Donnie’s enhanced senses picked up the fresh pearly cum splattered up the slider's plastron.

“You came again,” Donnie murmured, “just from eating me out.”

“I did,” Leo agreed. He wiped his hands and face off, then moved up next to Donnie and let him lick up the cum on his plastron. Both of them were satisfied and churring. They knew this was just the beginning, that they'd have to brace themselves for when the next wave of Donnie’s unrelenting heat pulled them back under, but for now they had a reprieve. For now they could just enjoy each other.

Chapter Text

Leonardo’s door was locked.

Donnie couldn't get the older slider out of his head. Ever since Casey Jones Junior came into this timeline and saved them all from a slow death by Krang apocalypse, Donnie had been curious about everything regarding the young time traveler, but especially the middle aged
veteran version of his twin Leo. He couldn't fathom how his reckless, immature, showboating brother could have grown up to be the leader of the entire Resistance in Casey's future timeline, and not only that, but also how he could have been a father figure to this boy, this child who’d
had to grow up too fast and resembled their father too much for it to be a coincidence. A simple test had revealed the truth: Casey was their future selves’ child, made from their combined DNA and Cassandra’s.

Maybe being a co-parent had forced Leonardo to set aside his childish ways and step up.

Maybe he’d wanted to do better than Splinter and be a proper father to their child.

A few months after the failed Krang Invasion, Casey's Sensei had materialized in a shimmery golden glow out of nowhere. The first thing he’d done upon learning his son had been successful was to request a (tearful) group hug and to promise he would be there for any of them at any time, no questions asked.

So Donnie had taken him at his word. He'd been spending a lot of time getting to know Leonardo as a person, asking as many questions as possible while making his new big brother a better prosthetic arm and designing his room, so he would have his own personal space and wouldn't need to sleep on the couch anymore.

When he’d finished installing the new arm and given Leonardo a tour of his brand new train car with all the amenities including a private bathroom, Donnie had just assumed he’d be invited into it sometimes. To his disappointment, Leonardo had thanked him for all of his hard work, and then never invited him back in.

Even so, the door was usually unlocked, and a few times Donnie had been forced to let himself in when Leonardo was needed for some team building exercise Raph and the younger Leo had decided, or was late for dinner. Those who grew up in an apocalypse simply did not skip dinner or Mikey would make them regret it. Casey and his Sensei were both all too familiar with Doctor Delicate Touch.

This time Donnie had wanted some alone time with the slider. He’d been thinking about broaching the subject of Leonardo’s relationship with his Donatello, to find out if they'd ever had casual sex the way he and his Leo did, and if he’d be interested in reliving his glory days with a younger version of his brother.

The damn door was locked. Donnie couldn't understand why he would say he was there for them at any time, then pull a stunt like this. So what if he was naked or doing something he wanted to keep a secret? Everyone knew the twins didn't keep secrets from each other. Shouldn't that apply to twins from different timelines too?

Wait. It was wrong, definitely wrong of him to do it, but Donnie had set up hidden cameras in all of their rooms in case of emergency, so they could be monitored if they were chronically ill or having nightmares, etc. And also to satisfy his own curiosity. He would usually only use them if necessary (Doctor Delicate Touch had hammered in the concept of privacy and personal autonomy until Donnie understood that he shouldn't spy on them whenever he felt like it) but Leonardo was behaving strangely, and he was concerned. He told himself that the older slider
might have gotten into a predicament and was unable to call for help.

“Activate ‘I’ve Fallen and I Can't Get Up’ Protocol,” he said quietly into his tech gauntlet, going back into his lab and locking the door so he wouldn't be disturbed. (And yes, he was aware of the irony. But he also didn't want to upset his brothers if it turned out nothing was actually
wrong.)

He sat down at his desk and watched the feed. He had two different angles in Leonardo's room.
One was aimed at his office/sitting area, and Donnie didn't see the big guy there. The other one was in the bedroom area and he could easily see if the bathroom door was open or closed. There were no cameras *in* the bathroom, but it was nice to know if Leonardo was in there in
case he’d fallen in the shower or something. But he also had a good side angle of the bed.

Right now, Leonardo was lying on his bed face down, using his reactivated ninpo to fuck himself with a softshell dick shaped dildo using portals to get the best angle, the other hand wrapped around his own impressively larger cock, precum and slick soaking him from tip to tail. He’d
propped himself up on a pillow so he could reach under to stroke himself, and Donnie could tell by the way his whole tail was glistening that he’d changed positions a few times. The cute appendage stuck straight up in the air, showing off his now gaping hole being penetrated
roughly over and over. Donnie started salivating as he watched Leonardo completely remove the purple phallus every third stroke or so and slam it back in, letting the flexible prongs at the end catch on his opening on the way in. There was no sound on the cameras, but he watched
Leonardo’s face contort with each violent entry, pain and pleasure combined. Tears and sweat streaked down his maskless face.

“Donnie!” he very clearly shouted, looking both aroused and guilty. Oh no, what did he have to feel guilty about? If he was truly a Donatello connoisseur, surely Donnie's counterpart had told him he was free to use him as spank bank material. He sincerely hoped Leonardo didn't have
some kind of hangup about it just because the elder Donatello was dead and *he*, Donself, was a younger man. He was an adult now, perfectly fine to fantasize about, guilt free.

He watched Leonardo start to lose control, fucking his fist and fucking himself so fast the dildo blurred, not even bothering to pull out anymore, just pistoning it inside of his asshole at just the right angle to hit his own prostate. Just as he started to cum, he slammed the dildo all the way in and yanked his hand out of the portal, closing it before he could do something really stupid like
portal chop himself. Donnie watched the older version of his twin cum fountains over his hand, and the dildo shot out of him as his muscles contracted rhythmically. When he was finished, Leonardo rolled over onto his carapace and starfished, taking up most of the bed with his long
limbs. The prosthetic arm twitched the same way as his other one, the aftershocks of his orgasm making his muscles tremble. The electrical impulses from his brain didn't differentiate between organic and synthetic, in this case.

Donnie waited. The slider eventually got up and went into the bathroom, presumably to shower. This gave Donnie a few minutes to pull down his shorts and drop into his own hand, already soaked from this whole situation. He stroked himself slowly at first, enjoying the buildup of
tension. His strong thighs quivered, even more so when he began to play with the sensitive tip, rubbing each petal with equal attention given, lighting up the pleasure center of his brain and pulling loud moans from himself. He wanted more. No, he *needed* more.

He used his other hand to text the younger Leo. ‘Can you portal into my lab and let me sit on your dick?’ He knew his twin was usually good for that, anytime.

He watched the little dots on the screen moving as Leo replied. He waited for a full minute before his twin's response appeared.

‘I think you’ve got the wrong Leo.’

Shit. He’d messaged Leonardo by mistake. Well, he could roll with it. ‘No, actually you would be the perfect version of my twin for the job right now. I repeat, can you portal here and let me sit on your dick?’

He waited impatiently for the following: ‘I’m too old for you, Donnie. It's not right for me to corrupt you. No matter how hot I think you are. Great Pizza Supreme, you are the hottest young man I’ve seen since my own Donnie was your age. You don't need a broken old turtle like me.’

Donnie gritted his teeth, suddenly frustrated. He *needed* that big beautiful turtle man and his gorgeous dick. He couldn't let him continue to think he was unworthy. ‘Just come in here. We can talk about it in person. Please. You said you’d be there for me.’ The last part, admittedly,
was a tiny bit of a guilt trip. But it was true. He felt rejected and it would do him a world of good to talk it out, even if Leonardo still refused his advances. At least he would know.

A moment passed, and then a portal appeared right behind Donnie. He turned around, hand still on his dick, and watched a still naked Leonardo step out, blinking in surprise, face reddening as he seemed to realize what he’d walked in on. The portal closed, and Leonardo just stared at Donnie’s lap for half a minute. When his eyes finally moved upward, Donnie smirked, not unkindly.

“I'm a grown adult, Nardo,” he said with as much patience as he could summon. “I'm not the kid you think I am. And I know what I want. I look at you and I see something extraordinary. Gorgeous. Delicious. I won't force you to have sex with me. But if you decide you would like to
try some fresh, hot Donnie, I promise you won't regret it.”

Leonardo’s pupils dilated as the smell of Donnie’s sex reached him, sweet and musky. Any further words of protest he might have had were overridden by his desire to please a Donatello, and he sank to his knees before Donnie, mouth watering.

“Can I taste you first?” he asked very softly, eyes big and shining and any guilt now replaced
with longing.

Donnie bit his lip and let go of his dick, watching it spring back into its natural hard position pressed against his abdomen. He held out his sticky hand to his elder twin. “Clean this first,” he instructed, heart beating a little faster. Sweet caramel macchiato, he loved a submissive Leonardo of any age. It did things to him.

Leonardo reached out to hold Donnie’s wrist reverently, lapping at his fingers and palm with slow, long licks, leaving nothing behind except for his saliva. Donnie’s breathing picked up and he had to shift in his seat, aching to be penetrated.

“All done,” Leonardo announced sweetly, staring up at Donnie, head bowed. “May I please have a taste, Sir?”

Donnie felt heat blooming from his groin outward, spreading in a tingling rush through his entire body. He flapped his hands, unable to contain the overwhelming feeling. He hoped the outward expression of excitement wouldn't make Leonardo think less of him.

“Yes, you may,” he said in a deeper tone, rough with desire. “But not for too long. If you want to make me cum, do it quickly.”

Leonardo whimpered quietly before choking it back, embarrassed. He took Donnie’s swollen cock in his hand and leaned down, swirling his tongue over the head. Donnie shivered and gushed slick all over his chair. He should have put down a towel. Oh well, couldn't be helped.
Fuck, it felt so good!

Donnie didn't get blowjobs very often, only on special occasions like their birthday, so he really, really appreciated it. Leo was good at giving head, able to deep throat like a pro. But Leonardo was amazing. His mouth was hot and so wet, the suction exquisite, his tongue in constant motion, knowing exactly how to stimulate him in the best way. Oh, his future self was a lucky man! Donnie could only imagine that he’d trained Leonardo at some point to give him perfect oral every day, hungry for it. The slider sure seemed famished for it. The way he bobbed up and down, doing all the work so Donnie didn't have to move, made the softshell let out so many sounds, turtle and human, that would have been embarrassing if it were with anyone else. And the way Donnie came so fast, so hard, in powerful spurts, quaking from the intensity, was
something he’d literally never experienced before.

Donnie wasn't much of a crier, especially during sex with Leo, but something about this moment with Leonardo was making his lip wobble and tears spill down his face. Maybe it was knowing what he’d been missing out on, what he’d denied himself by keeping things casual with Leo, that was getting to him. It was so much better than just a casual fuck. Leonardo looked at him like he
was the prettiest star in the sky, and it broke him.

Donnie hid his face in his hands and took slow shuddering breaths, composing himself. He felt Leonardo pull off of his dick, leaving a tender kiss on the tip, and heard the faint sounds of him wiping himself off. Then he felt the slider pull him down onto the floor, into his lap, and cradle
him in his arms, making soothing churring noises.

“I’m sorry,” Donnie whispered after maybe 5 minutes of slow steady breathing and listening to Leonardo’s comforting churrs. “I was not intending to ruin the mood. You surprised me. I was unprepared for your advanced skill level, among other things.” He dropped his hands and
looked up at him, vulnerable. “You love me.”

Leonardo’s expression was so gentle and caring. “Of course I do. My idiotic younger self loves you too. He’s just really bad at showing it. I have a lot of experience with loving a Donatello.” He smiled and wiped Donnie's face with his thumbs. “Do you still want to sit on my dick, or has that ship sailed?”

Donnie’s heart skipped a beat and he smiled, rising up on his knees to bump his forehead against Leonardo’s. “I really, really want to ride you. Where would you like to do this?”

Leonardo’s hands moved down to rest on Donnie's hips. “We can do it right here if you're comfortable on my lap.” He rubbed Donnie’s scales with his big hands, making the softshell churr and melt against him.

“I want you,” Donnie murmured, kissing his neck. “Please, Nardo!” He moved a hand down, rubbing Leonardo's slit with his palm, using the heel of his hand to apply firmer pressure. He felt the slider getting wetter, and then the head of his cock pushing out. Donnie coaxed it the rest of
the way out with gentle rubs and soft sexy whispers of what he wanted to do to Leonardo.

The big slider worked him open with fingers coated in slick, then pushed up into him and let Donnie sink the rest of the way down at his own pace.

They both trembled and moaned as Donnie took Leonardo all the way to the base. Then they moved together, holding onto each other tightly, giving each other sloppy kisses as Donnie bounced on his big dick. It stretched Donnie so nicely. Leonardo couldn't believe how hot and wet and tight Donnie was.

When they came together, Leonardo tried to pull out but Donnie didn't let him. He loved the feeling of a Leo filling him up with luscious cream. Nothing compared. To his delight, Leonardo filled him with even more cum than he was used to. Donnie spurted all over his bigger twin’s
chest.

As they recovered from their climax, they became aware of a weak-kneed smaller slider sitting by a portal, having fallen through at the moment of his own orgasm. When he realized they’d noticed him, he gave them a quick thumbs up with his clean hand.

“1000/10, beautiful, would watch again!” Leo said with a sheepish grin.

“Next time you're joining us,” Leonardo responded with an answering grin, and Donnie nodded in agreement.

Chapter Text

Leo laughed nervously. “Hahahaha you’re so funny, bro! Can you let me down now? I promise I won't mess with your gorgeous artwork anymore!”

Mikey smirked, although his eyes were pure hellfire and damnation. He tightened his glowing chains around the red-eared slider who was suspended from the ceiling in the middle of the training room, naked and spread eagled. The chains were looped in an intricate pattern around his upper arms, thighs, and under his pectoral scutes, among other places. Mikey had made sure to leave his genitals, ass, and tail exposed.

“Not good enough, Leon!” Mikey chided. “You destroyed my stunning self portrait, and for that you have to pay! Donald?”

Donnie stepped forward, face neutral, holding his tech bo. He studied Leo’s exposed body, walking around him to get the full view, taking his time. Without warning he smacked Leo across his exposed ass with his bo.

“AAAAHHHH! Fuck, that hurt, Dee!” Leo yelled, twitching.

“Scoff. Did it hurt as much as you wounded Michael's artistic pride, Nardo?” Donnie sneered, moving in closer and smacking Leo with his hand right over his cock slit. The slider screamed, shuddering, dripping slick already as he struggled not to drop into Donnie’s waiting hand. Tears started to pool in the corners of his eyes from the pain and the humiliation.

“I didn't mean to!” Leo protested, voice cracking.

“But ya did,” Raph intoned in his most serious big brother voice. “And now ya need to take responsibility for your actions, Leonardo. It's time to take your punishment.” He carefully lubed the handle of one sai (he’d bought these specifically for just such an occasion) and pushed it into Leo's unprepared ass, holding it in place. “Raph’s gonna make sure ya remember this!”

Leo had gone hot and cold with fear and arousal. The cold metal and warm leather of Raph’s sai handle inside of him made him want to squirm, but he was also afraid to do so. Donnie was still in front of him, and now he was mostly staring at Leo’s wet slit, giving him seemingly random whacks with the bo or his hand, across his slit or his chest or his thighs. It was getting so hard to hold still.

Raph took the other sai and delicately dragged its prong along the backs of Leo’s legs. He exerted a little more pressure when he got to his calves, and the lightest pressure behind his knees. Leo whimpered, not knowing what to expect at any moment.

Mikey stood back and observed, the tiniest smirk still on his lips. “Color, Lee?”

“G-green,” Leo choked out, head thrown back, tears and drool on his face. As Donnie landed a perfect hit on his emerging cock head with a well timed flick of his finger, Leo lost the battle and dropped completely, sobbing. The softshell seized the opportunity and wrapped a steady hand around his exposed length, jerking it roughly.

“Aaaahhhh fuck, Donnie–” Leo began, but then his twin shoved two fingers of his other hand into his mouth.

“Suck,” Donnie ordered flatly, almost sounding bored.

Leo rushed to obey, sucking hard on Donnie's fingers, lapping at them, soaking them in his saliva. They tasted like salt and metal and Donnie's own musk. Oh. His eyes widened. Donnie had been touching himself before this. If he focused, he could smell Donnie’s pussy through his tight shorts. Wet and hot and probably aching.

As soon as Leo’s mouth was free he blurted out, “Please let me eat you out after this!”

A slight break in his composure, a bead of sweat and a slight blush, and Donnie’s mouth curved upward. “Only if you take your punishment like a good boy, Nardo.” He slowed his strokes, loosening his grip. His saliva coated fingers pushed into Leo's cock slit directly under his swollen shaft, and he fingered him deeply, thrusting in and out rhythmically. “You are not allowed to cum until one of us says so.”

Leo’s toes were already curling and he panted loudly, overwhelmed by sensation. He leaked a constant stream of precum and slick that left a growing puddle on the floor. His hands balled into fists. “That's gonna–fuuuuck—gonna be really *hard*, Dontron,” he managed to groan out. “I-I don't know if I c-can hold back.” He was shaking so hard that Raph had trouble keeping from stabbing him in the leg, so the big snapper was just fucking him slowly with the sai handle in his ass.

“Oh Leo, you're shaking. Are you cold?” cooed Mikey sweetly. “Let me warm you up.” He ignited the chains with mystic fire.

Suddenly Leo couldn't hold still no matter how hard he tried. It was futile to try to escape the flames, but his body fought to get away reflexively. He was outright sobbing now, and Donnie had started stroking him faster, feeling a little bad for his twin and wanting to soothe him. (While also sabotaging his efforts not to cum.)

“Fuck fuck fuck pleeeease, please stop Mikey, I’m sah-ha-hahrryyyyy, I didn't mean to, I won't ever do it agaaaaain!” Leo whined, writhing and tensing in every direction.

Mikey lowered the temperature but didn't shut off the flames yet. “Are you going to respect me and my belongings from now on? And promise me you won't touch anything in my room without permission?”

“YES! I PROMISE!” Leo begged, face hot with shame and the heat of the mystic flames licking at his scales like little tongues. “Please Mikey, I’ll do anything, just let me cum!” He was almost there, with Donnie’s soft exhales caressing him like a cool breeze compared to the fire. When Raph leaned in to bite his ass cheek and Donnie twisted his fist in a particular way, Leo squeezed his eyes shut and blurted, “Yellow!”

Everyone paused, hands staying where they were. Mikey made the flames disappear, and Leo just stopped and caught his breath.

“Do you need anything?” Mikey asked, dropping the cruel persona.

“Water, please,” Leo requested, opening his eyes to look at his twin. Donnie immediately used one of his spider arms to pull a water bottle out of his battle shell. Mikey opened it and put a straw in it, and Donnie held it up to Leo’s lips with his metal claw.

After he’d drained most of the water, Leo felt better. “Done,” he said in a rough voice. “We can continue.”

Donnie withdrew the bottle and the spider arm, and resumed his motions with both hands, looking up and watching Leo’s face. Raph was leaving love bites everywhere he could reach, and had resumed fucking him with the sai.

Mikey concentrated until he was floating in front of Leo in a lotus position, their faces at the same level. He leaned in to kiss his brother gently. Leo’s eyes grew shiny. He kissed back eagerly.

“I think you’ve been punished enough,” Mikey decided. “Gentlemen, finish him. Leo, when you're ready, cum for us.”

Leo gasped and moaned as his brothers all brought him to the brink again, and this time he went flying over the edge, covering a surprised Donnie’s face and hands in cum. He felt so good, it made up for all the suffering from his punishment.

Mikey let him down slowly after he was free of all hands and objects on and in his body, and Leo stretched his limbs, trying to get his circulation going again. Donnie disappeared for a moment to clean himself up, and when he came back, he helped wipe Leo down too.

Raph gave Leo a loving kiss before leaving to clean off his sai.

When Donnie tried to leave again, Leo caught his arm. “Donnie, I haven't forgotten about you. Do you still want me to eat your pussy?”

Donnie froze and looked guilty. “You…don't have to if you don't want to. We pushed you too far.” But he was shifting his weight, thighs pressed together, like he needed some relief.

“I want to,” grinned Leo. “C’mon, let’s find somewhere more comfortable.”

They ended up in Leo’s bed, Donnie lying on his back with his legs hanging over the edge, ass propped up on a pillow, sopping wet shorts off. Leo knelt on the floor between his twin’s legs and breathed in the delicious aroma of a very aroused Donnie.

Donnie stared at Leo with loving eyes as the slider opened him with his tongue and fingers. He licked his soaked cunt from his tingling clit down to his needy hole, and made happy chirping noises when Donnie hugged his head with both thighs.

It didn't take long for Leo to bring him to a shattering orgasm, fingers buried inside of him curling against his sweet spot, lips and tongue and joyful humming and churring making him whimper and cry out and flood Leo’s mouth with his sweet cum.

When Donnie was finished, he pulled Leo up into his arms and kissed his face all over.

“Your mouth is your secret weapon,” Donnie declared, smiling. “You wield it well.”

Leo could only smile back, delighted and a little smug.

Chapter Text

Everything was too loud.

Leo couldn't follow the conversation anymore. He’d been trying to keep up his Face Man persona during the party, but his head was starting to hurt from the noise and he felt itchy all over and a little dizzy. His vision was tunneling and he was afraid if he stayed here any longer he would faint or do something worse like have a meltdown.

The worst thing about this was that his brothers and April were having a great time. Even Donnie, who had a 50-50 chance of bailing out in the first hour if the atmosphere got too chaotic, was dancing with Sunita and telling her about his latest improvements to…something. Leo honestly couldn't figure out what he was talking about. His vision was too blurry to read lips and he really needed to get out of here before he embarrassed himself.

They were at Run of the Mill, at Sunita’s Grand-Googly’s birthday party, which also happened to be her birthday, but she didn't want to make a big deal out of it because she just wanted the old Yokai to have a great time. Señor Hueso had donated space in the banquet room, and Donnie had consulted with Sunita about the music. Turned out Grand-Googly was hard of hearing and mostly liked music with a good beat and lots of bass. So much bass that it made Leo feel like his molecules were vibrating. (Man, he felt so much like Donnie right now.)

Leo got out his phone and texted his twin. ‘Gonna bail before my head explodes. Tell Sunita I said Happy Birthday. I’ll make it up to her another day.’

He watched Donnie glance at his tech gauntlet and frown, then say something to Sunita. She looked worried, and answered him back with a reassuring pat on his battle shell. He leaned in and gave her a quick hug before pulling back and disappearing into the crowd.

Leo left the restaurant and tried to make a portal home. It wasn't working very well. The feeling of his scales crawling hadn't gotten any better now that he was away from the noise, and he winced, narrowing his eyes to slits to block out the light from the setting sun. He took a few deep breaths and tried again. Finally, he was able to portal home, although he fell through the portal and landed on Donnie’s bed instead of his own. It was dark and quiet, and the bed was comfortable, with nothing scratchy or strong smelling. The only thing he could smell, in fact, was Donnie’s pleasant scent.

He quickly undressed and buried his face in his twin’s pillow, covering himself with the heavy weighted blanket. Gradually the itchy feeling went away and his head started feeling better.

He drifted off to sleep, comforted.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Donnie made sure to let the rest of the family know he was leaving to keep an eye on Leo. He left his credit card with April so she could settle the bill after the party, and took the quickest route home, flying most of the way. He checked all of Leo's usual spots, and when he didn't find his twin, he went into his own bedroom on a hunch.

He flipped on the purple ambient lighting and went over to his bed, walking as softly as he could. Leo was wrapped in his weighted blanket, face turned into his pillow, snoring faintly.

Donnie undressed, only leaving his mask on, and got into bed with Leo. The slider stirred, turning his face and blinking at Donnie.

“You're home,” he whispered. “You didn't have to leave. You were having fun.”

“Not without you,” Donnie whispered back. “Not knowing you were feeling unwell. How do you feel now?”

“Better,” Leo admitted, lifting the blanket and inviting him underneath. Donnie took advantage of the offer and moved in to hold Leo, snuggling close.

“Sensory overload?” Donnie queried, hand moving to tap against Leo's face and neck in a soothing pattern tailored to his red-eared slider instincts. It was a behavior used in courtship, and it always distracted Leo from his discomfort. Sometimes it put him in an amorous mood, but at the very least it would give him a relaxed feeling and the impression of being adored. Which he very much was.

Leo swallowed hard, churring softly. “Y-yeah. Too loud. Too much.” He stared into Donnie’s eyes and licked his lips. “Dee, can I suck your cock?”

Donnie nodded slowly. “Yes, of course. How do you want me?” He was already naked, which meant that it was easy for Leo to move a hand between his legs and stroke his slit gently but firmly until he dropped with a little grunt.

“On your back,” Leo whispered, guiding him into position. “Knees bent, legs open.”

Donnie obeyed, and Leo disappeared under the blanket to get between his legs, kissing each soft inner thigh before taking him in hand and licking the very center of his multipronged head, right where he was dripping precum. The prongs tried to close, capturing his tongue, but Leo smiled and licked them all one by one, making Donnie’s legs shake and his hands grip the sheets.

“Fuck!” Donnie exhaled explosively, eyelids fluttering shut. “Leo. Do that again.”

Leo let out a quiet chuckle and repeated the action, treating Donnie to the unique sensation over and over, until the softshell arched up and whined.

“STOP!” Donnie cried out louder than intended. “If–if you’re planning on doing more than that, please p-proceed.” He was so wet now, slick pouring from his slit, as well as the trickle of precum traveling down his shaft in spite of Leo’s tongue catching as many drips as possible. There was just too much for the slider to manage, and it was starting to pool beneath Donnie, leaving a big wet spot that was spreading. He could feel it.

“Heard,” Leo said before taking Donnie down his throat in one quick motion. He swallowed around him several times, then began to move up and down on his length, churring and humming. After a minute he pushed the blanket off.

Donnie pushed his thighs together slightly, trapping Leo in place. The slider seemed to enjoy it, churring louder, hugging his legs. His tongue wriggled against Donnie’s shaft as he moved.

It felt like Donnie was almost there, but he needed something more. He chirped desperately and grabbed Leo's hand, guiding it to his tail.

His twin understood immediately; he stroked and squeezed his tail roughly. He even scratched it, setting off a chain reaction in Donnie. The softshell growled, thrusting upward, fucking his throat. Seconds later he came with a loud moan, spilling into Leo's waiting mouth.

Leo swallowed everything, then kissed his way up Donnie’s body and fell to the side, clinging.

“Did that help?” Donnie asked, turning to kiss him, not caring that Leo tasted like cum.

“Yeah, it calmed my brain down. I needed that.” Leo sounded sleepy and content. “Thanks for being here.”

“My pleasure,” Donnie hummed, kissing him deeply.

They took a nap together, and then after cleaning up, emerged to have leftover cake that Mikey brought home for them. Leo was glad to hear that they hadn't ruined the party by leaving early. Everything had worked out in the end.

Chapter Text

Donnie walked through the lair at his usual speed, heart beating too fast, face neutral but eyes a little too wide. He knew what was coming, vaguely, but he didn't know exactly how it would play out. He wondered how his brothers would break him.

Lost in thought, he didn't see the massive turtle in the doorway until he slammed face first into a solid chest. Ouch. He backed up and rubbed his sore snout.

“Raph. My apologies. I didn't see–”

“Ya didn't see me. The biggest turtle in this lair. Are ya sure ya can see at all, Donnie? Do ya need to start wearing glasses again?” mocked Raph, face twisted in a sneer. “Make ya look like even more of a nerd.”

Donnie huffed in embarrassed disbelief, folding his arms across his chest. “That's rude! My mind was simply elsewhere. It's not like I could hurt you anyway, as big and strong as you are!”

“Heh, that's right, Donnie! I am big and strong, much bigger and stronger than ya can ever dream of bein’. Look at that scrawny body.” Raph wrapped an arm around Donnie and lifted him up, carrying him like a football. “I can do whatever I want and there's nothin’ ya can do about it.”

Donnie felt hot all over, a strange mix of humiliation and arousal. “Stop it, Raph!” he protested weakly. He was getting wet between his legs, and he didn't really want Raph to stop, but he also didn't want to be seen like this, especially by Nardo.

Instead of carrying him off to bed like he expected, Raph brought him to the turnstile area where everyone else was waiting.

Leo held his swords and twirled them playfully. He sheathed one and used the other to cut a portal at their feet. Donnie’s stomach dropped just before he and Raph did, followed by Mikey, April, a masked Casey Junior, and finally Leo himself.

They landed in the middle of a sex dungeon, or maybe just a regular dungeon. There were drains in the floor, chains in various places, hospital beds and metal tables, and any number of scary looking devices and instruments. Donnie suddenly felt like he might piss himself.

“Raph, let me go! I have to pee!” he told his big brother, squeezing his legs together tightly.

“Go ahead,” Raph shrugged, yanking off Donnie’s shorts and holding him hovering over one of the drains, arms pinned behind his back.

Donnie’s face burned as he noticed all the eyes on him. He had no choice, though. He spread his legs and tried to focus on relaxing enough to go. It didn't work.

Mikey stepped forward and held his thighs apart, looking directly at his cunt. “What's wrong, Dee, feeling shy? Maybe I can make you forget to be a person. You can be my pet. And pets piss where they're told to.” He moved his hands down between Donnie’s legs and started fingering him roughly. He kept slamming his fingers into his G-spot, making Donnie squirm and whine. Oh no, Mikey was about to make him cum and squirt and probably piss himself in front of everyone!

“Nonono please don't! Don't make me do this with everyone watching!” Donnie begged, panting and starting to make obscene moans and grunts. He’d never been this turned on before; the degradation and forced obedience really made him lose control. He tried desperately to hold back his orgasm, but then Mikey rubbed his clit in gentle circles that contrasted with the otherwise rough treatment, and his whole body lit up with pleasure and intense release.

Oh fuck, he was soaking Mikey’s arms up to the elbows, powerful squirts coming out in waves, and when his orgasm ended he was pissing like a fountain, completely missing the drain.

Mikey stepped back, watching, accepting the warm wet towel Casey gave him to wipe his hands and arms with. He smirked evilly.

“Wow, Dee, gotta work on that control. Even simple animals know how to aim,” he remarked.

“Not like you gave me a choice,” Donnie choked out, completely drained and quivering. “Sadistic!”

“That's me!” Mikey grinned. “Casey, got the hose?”

Casey stepped forward with a long hose with a sprayer attachment, and set it on high pressure. He turned it on and aimed it at Donnie's pussy, concentrating it mostly on his clit.

Donnie bucked and writhed, trying to get away from the unrelenting spray that hit his oversensitive nub. It was surprisingly warm but the pressure was too strong. It made him want to scream. Raph held his arms tighter, and Leo and Mikey held his legs open so he couldn't avoid the assault. The water washed him clean and rinsed his puddle down the drain.

Unfortunately it also set off another almost painful climax that made Donnie sob and gush slick down to his tail.

Leo’s eyes sparkled with excitement and anticipation. Casey shut off the hose, and the slider ordered Raph to move Donnie to a bed. As soon as Donnie was on his back, Leo got between his legs and gave him an appreciative sniff.

“Perfect. Your slutty cunt is ready for me. So wet and just begging for a good pounding,” he churred. He pulled his own shorts down and dropped, giving himself a few good strokes while Donnie watched him with wet, hungry eyes.

“Ahhh fuck, I'm gonna make you wish my cock could live in you 24/7!” Leo promised, pushing into Donnie’s warm wet passage an excruciating inch at a time. “So tight, what have you been doing all this time, fucking pencils? Couldn't get anything bigger?”

Donnie’s arms had a mind of their own, trying to encircle Leo’s carapace as he finally bottomed out. Leo shrugged him off. “Oh no you don't, Donatello, I never said you could touch me!” he chided.

Donnie withdrew his arms quickly, shame hitting him like a slap in the face. He let out a sad chirp. “Sorry! I didn't–”

“Shut up, fuck toy, just let me fuck you!” Leo groaned, slamming into him at a quick, hard pace. Donnie gulped and choked back his words and his whimpers, letting his arms fall to his sides. He was so hot now, his brain could barely function because all of the oxygenated blood had risen to the surface in a full body flush. His sore pussy tingled with friction and with it he felt constant pleasure.

“Good, he knows his place now,” April observed with a sinister laugh. Donnie’s gaze moved to her, and he noticed she’d stripped down to her lacy yellow bra and a harness that held a long dildo around the same girth as Leo's dick. She shook her hips, making it wiggle for him. Donnie’s mouth watered and fell open, drool trickling out of one corner.

“Hungry for my cock, Deedee?” April asked condescendingly, sweet with a mocking undertone. “It's not enough that you want me to hang out listening to all your nerd shit all day, you wanna be *lovers* too? You want a taste of me? Don't worry, Genius, I’ll let you suck my cock before I put it in you.” She moved close and took his hand in hers, holding it. “Aww, you just want someone to love you. Poor widdle turtle boy.”

Donnie swallowed his pride and answered with a tremble in his voice, “I would do anything for you, April.” His breath stuttered and he arched off the bed with a loud churr, coming again.

Leo pulled out of his twin with a grunt and spurted his load onto Donnie’s plastron. “Are we recording this, familia? Who’s filming?”

“I got it!” Casey called out cheerfully, his mask camera on, catching every moment.

Donnie sucked in a sharp breath and started shaking all over. His muscles felt like jelly. Mikey swooped in with a cup of flavorless juice and ordered him to drink. While he was drinking, Mikey cleaned him off and applied some soothing ointment to his slit.

“April, give his pussy a break,” Mikey told her with a wink. “You can take his sweet ass.”

“Roger that, Mikey!” she replied, saluting. She pulled Donnie off the bed and onto a thin cushion on the floor. “Suck my dick, Lover Boy. And don't stop until I tell you to.”

Donnie obeyed her, taking her entire artificial dick down his throat with no hesitation. Saliva pooled in his mouth and ran down his chin as he let her grab him by the mask tails and fuck his throat. He didn't have a gag reflex but she was probably going to leave him with a sore throat and mouth. He focused on licking and sucking as she thrust into his face, making satisfied little growls.

When she pulled out, Donnie’s face was soaked with tears. He turned around and got on all fours, tail up, presenting his ass like a prize.

“Well, would you look at that?” April cooed. “How adorable! He thinks I'm gonna get on the ground to fuck him. Raph? Pick him up and bend him over the table.”

Donnie felt his big brother lift him up, carrying him over to a metal table, and position him so he was standing, bent over. Raph smacked his ass, making him jump.

“Be a good little whore for April and I might go easy on ya, little brother,” Raph told him, dipping a giant finger in Donnie’s dripping slick and pushing it inside of his ass, prepping him briskly.

Donnie was so sensitive from everything, he almost came when Raph pulled his finger out. He shuddered and bit his lip hard, squeezing his eyes shut.

April slipped in before he could even prepare himself. She’d squirted some lube on her dick, so it went smoothly enough that it only hurt a little. The stretch still burned. Donnie buried his face in his folded arms and took it, quiet hiccuping sobs shaking him. He was so overwhelmed and didn't want any of it to stop.

“Color?” April asked, stopping once she was buried in him.

“Green,” Donnie whimpered, pushing his ass against her. “More please!”

April rested her hands on his hips and gave him a little squeeze. “You got it.” She rocked into him with more gentleness than she’d planned, recognizing how far they’d all pushed him. Maybe after they finished this scene, she’d treat him to a nice relaxing spa session.

“Raph,” Donnie sniffled, “c’mere, I have hands. I can make you feel good.” He lifted his head and made grabby hands at his brother.

Raph moved in front of Donnie, already dropped and naked, and the softshell took his big beautiful cock in both hands and jerked him off lovingly, not meeting his eyes, too focused on his task. He wasn't sure if he could take much more, as sore and emotionally wrung out as he felt, but he knew he could at least get his big brother off, even if he could only do it this way.

Raph’s big hand rested on Donnie’s head. “Hey, if ya need to stop, remember we won't get mad,” he said in a hushed voice.

“I can do this,” Donnie insisted, tears still falling, warm all over from being forced to take so much cock and degradation. He was starting to feel fuzzy from it. He coaxed Raph a little closer so he could lick his big cock head, stroking him steadily.

April sped up, her thrusts getting sloppier as she began to cum just from the thrill of taking Donnie, and she threw her head back and yelled “Aprilllll O’Neil!!!!”

Donnie snorted and shook his ass against her in congratulations. He worked Raph up to his orgasm, and happily swallowed the flood of cum. He himself didn't have it in him to cum again, but he was happy to help.

He glanced over to see Mikey and Casey fucking against the wall, Leo wearing the mask now and recording them. Casey was holding Mikey up, buried in his ass, kissing him as he moved in slow thrusts.

April pulled out of Donnie and planted a kiss on his tail, then gently cleaned him up. She and Raph wiped themselves down, and Raph picked Donnie up and held him, taking a seat so they could watch the show. It was mesmerizing.

Fifteen minutes later, everyone was cleaned up and covered up, and Leo portaled them to Raph’s train car. They took turns in the shower, and Leo was the one who carried Donnie to the big bathtub and cuddled with him in the hot water, giving him all the touching he’d denied him earlier.

Clean, dry, and wrapped in soft blankets and loving arms, Donnie drifted, listening to Leo's heartbeat and Raph and Mikey’s churrs, and the soft words of April and Casey telling him what a great job he’d done.

The next day, Donnie let himself be pampered with breakfast in bed, first pick of movies, and anything else he wanted. What he wanted the most was quality time with his family. He spent one on one time with everyone, and let himself recuperate from what was a very fun but exhausting experience.

At the end of the day, they made plans for next time. Next time, Leo would be the victim. Donnie couldn't wait.

Chapter Text

There was a ghost in the lair.

Ever since he and his siblings had learned to connect to their ninpo and met the Hamato spirits, Donnie had been forced to concede that ghosts were real.

Lately, ever since the Krang, he’d been waking up out of nowhere feeling cold, and sensing that someone or something was in his bedroom. It was a nightly thing, and although he hoped he would turn on the light to see a familiar face, whoever was visiting never showed themself. He would barely catch a glimpse of glowing green, and then they were gone.

As much as it pained him to do so, he had to seek outside help, so he started asking Mikey or Leo to stay with him at night. He kept his goggles nearby, so he could turn on the night vision setting and not have to turn the light on. And he had to admit, it helped to have a brother in his bed, someone to hold him when he was chilly and (dare he say it) afraid.

He wished he had the option to summon Raphael. His big brother had always been the most comforting to him, with big, strong arms that gave the best hugs and carried him when he wasn't feeling his best. Donnie couldn't ask Raph to join him in his small bed that was even a little tight of a squeeze for him to share with Leo.

He missed being able to crawl into bed with his dad. Splinter, although he’d had his depression era, was always happy to share his bed with a scared or unwell turtle. Even when he was outright neglectful, he’d been a comfort in the middle of the night after a bad nightmare, and Donnie could kick himself for deciding at the ripe old age of 14 that he was too cool to go to Splinter anymore. He was older now and didn't need his Papa to soothe away the scary images and bad feelings.

It was too late now. Even if he wanted to, Donnie couldn't go to him. He was seized with a strong urge to cry, but he swallowed it back and rolled over to bury his face in his twin’s neck, holding on tight.

“Dee? You ok?” Leo asked sleepily. He gave Donnie’s carapace a hesitant rub through his pajama top.

Donnie didn't answer with words. He churred quietly and squeezed his eyes shut against the burning sensation. He didn't want to talk about it. He just wanted some comfort from his other half. His better half, although he only said it when he was in a sappy mood, when they were holding each other after making love and Donnie had the irresistible need to worship his Nardo. It was in those moments that Donnie felt the most vulnerable and hoped that if he treated Leo right, said the right words, he might actually get to keep him.

Leo kissed his forehead and hummed softly. Donnie began to relax and drift off to sleep. He felt warmer now, safer, wrapped in his twin's embrace. Nothing could hurt him.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

“Daddy?” Leo said in a quavering voice.

Donnie woke up instantly, pulling back and grabbing his goggles. He switched on the night vision setting and looked at his brother first.

Leo was staring, eyes wide and wet, at someone Donnie was afraid to try to look at, lest he scare them off. Of course it would be Splinter, here to watch Donnie at night but never actually show himself to the turtle who needed him the most. He had no problem revealing himself to Nardo, apparently.

Donnie let his eyes flicker over to the apparition. If he didn't call attention to himself and was very, very still, he could just barely see the familiar shape of their father. He was the same as he had been in later life, short and grey and pudgy. He was looking at Leo with so much love and regret, letting his eyes do the talking.

Leo reached out to Splinter with tears pouring down his striped face, and the ghost moved closer, resting a hand on the slider’s cheek. Leo gasped and covered the hand with his own. “Daddy, I missed you so much!”

Splinter spoke then, and it sounded strange, like an echo. “Oh my sweet Blue, I am so sorry I couldn't stay.” He embraced Leo carefully.

Donnie lay frozen, only daring to look directly at his father when the old rat was distracted. He wanted to join in, hug him, see if Splinter would give him a kind word, but he was afraid to scare him off.

Ha, the irony.

He finally got the courage when Leo and Splinter broke apart after a whole quiet conversation he’d missed, lost in his own head.

“Papa?” he whispered, reaching out.

Splinter’s gaze turned devastated and apologetic, and before Donnie could blink, he was gone.

Leo’s expression was sad and compassionate. “Donnie, I’m so sorry.”

Donnie’s hand dropped, and his breathing stuttered, heart breaking. “Why won't he stay for me?” he cried, ripping off his goggles and putting them back on the nightstand. “What did I do wrong?”

Leo hugged him tightly. “It's not your fault. You didn't do anything. He’s just being stupid, ok?” He sounded unsure but determined. “I’ll make him stay for you next time.”

Donnie shook his head. “What if there isn't a next time?” He pulled away from Leo but extended a hand. “I need to find out if he's visited Raph or Mikey.”

Leo took his hand and they walked to Raph’s room. The door was open slightly and they could hear Mikey talking.

“Dad, you need to stop running away from Donnie!” Mikey scolded. “I don't care how guilty you feel about letting him down. You're makin’ it worse! You know he always blames himself!”

“He’s right, Pops!” Raph agreed, disappointed. “Ya need to apologize and tell him how ya really feel!”

“What is the point? I have already hurt Purple enough. He doesn't need me. He has always needed his brothers.” Splinter sounded resigned. “Red, you have been a better father to him than I ever was.”

Donnie’s fury lit up and he shoved the door open, stomping in. “NOT SO FAST!” He activated his ninpo, forming a solid bubble around Splinter. The rat tried to escape, but apparently Donnie’s love for his family was strong enough that it broke supernatural laws.

“Ha! You are no match for my Ghost Jail, patent pending!” Donnie announced with a bitter smirk. “Papa, I say this with the utmost respect and love. You are being a dum dum. First of all, how dare you put that on Raphael?! It's bad enough that you expected us to take care of ourselves with next to no parental involvement except when it was convenient for you. But you also expected our big brother, who is just barely older than us, to be a surrogate father, to the point where he can't be alone or he gets weird, and he worries constantly about things he can't control. Which I’m sure Doctor Feelings would agree is unhealthy and not good for his development.

“Second, when have I ever not needed you? Were you so lost in your stories and your joyrides in stolen vehicles that you didn't see me constantly trying to spend time with you? You didn't need a brand new remote control every week, or an upgrade to your chair, or any number of things I provided so we would have something to talk about, even just for a minute. I needed you. I still do. What I wanted was for you to be proud of me, want to get to know me, listen to me. Even if you didn't understand a word of my infodumping. Even if you weren't perfect. I just wanted my dad, not a boss or a roommate or a superhero. Some of my best memories of you were when we would just spend a few hours together doing, I don't know, normal things? That one time when Leo and I turned six and you snuck us all into a movie stacked together in a trenchcoat?

“Third. You’re dead now and I can't even try to talk to you without you running away. Do you know how much that sucks? Most people can't talk to ghosts. We are so lucky. And yet you've decided it's better if you avoid me forever because you feel bad about hurting me? Well, guess what, Dad? This is worse! Stop being a coward and let me love you! I’m really starting to think you don't like me, and if that's true just tell me! But don't hide behind some crappy excuse just because you’re afraid of getting yelled at.”

Donnie stopped and took a few slow, steadying breaths. His brothers all stared at him, wide eyed. Ok, maybe they’d never actually seen their usually emotionally avoidant brother pour his heart out and scold their ghost dad like this. Ever.

Splinter was gaping at him, positively gobsmacked. He reached out with one hesitant hand. The bubble gradually expanded until it enveloped Donnie too. The softshell met his father halfway, kneeling to wrap him in his arms. Splinter embraced him, kissing his temple.

“You are right, as usual, Donatello,” Splinter sighed. “I am so sorry for being a coward and a neglectful father. I know I cannot possibly make up for it, but I will do anything I can to help you heal from what I did to you. And that starts right now.” He patted Donnie’s carapace comfortingly. “What do you need?”

Donnie buried his face in Splinter's shoulder and spoke, muffled. “If I drop the bubble will you promise not to disappear?”

“I promise I will stay as long as I can. And I will come back as often as possible,” Splinter responded. “It does take a good amount of energy to remain solid.”

Donnie gave him a final squeeze and pulled back, smiling now. “That's all I ask. Quality time.” He dropped the bubble. “Can you stay longer if you’re not solid?”

“I…think so,” their father said slowly, matching his smile.

“Very well. Brethren, I know we all crave Father’s hugs, but try to restrain yourself for his sake. One hug per turtle per visit, perhaps? More only as needed,” Donnie said casually, glancing at his brothers.

They were all wearing identical teary, proud smiles. Donnie rolled his eyes. “Ok, fine, just this once, I authorize a group hug.”

They all came running, squishing Donnie and Splinter in the middle of a tight hug. The siblings stayed in the hug until Splinter started to get transparent around the edges. Reluctantly, they let go.

“I must rest. You should, too. It is late,” Splinter told them. “But I will return.”

He turned to Donnie, a warm smile on his face. “Oh, and Purple? I have always liked and loved you very much. I will say it as many times as you need to hear it.”

Donnie beamed, and accepted one last kiss in the middle of his forehead before Splinter faded away.

Later, his brothers would express their admiration of Donnie, and of the way he’d called Splinter out in a way that rivaled Mikey in his use of emotional honesty. But for now they gathered into a turtle pile in Raph’s bed, and Donnie slept better than he had in a long time, unburdened and loved.

Chapter Text

As Leo’s fingers began to tire, Donnie wrapped a hand around his wrist and kept him there, two fingers buried to the third knuckle inside of the softshell's sloppy wet pussy. He was straddling Leo's lap, head resting on his shoulder, desperate little gasps and whines occasionally breaking the near silence punctuated by the bed springs creaking or the occasional plapping noise of digits moving through slick.

Leo had started out intending this as a reward for Donnie being a good and attentive lover the night before. He was just going to finger Donnie to a few satisfying orgasms, then maybe excuse himself to go jerk off in the shower. But his twin wouldn't stop or let him go. He was on his sixth orgasm now, using Leo’s thumb to grind on as the slider just kept going, even as his hand muscles burned.

“One more, Dee, then maybe you’d like to take something a little bigger?” suggested Leo in a breathy, seductive voice. He could already tell his shorts were ruined, soaked in his own fluids. He’d dropped a while ago, and came in his pants once, so aroused by the sounds and the scent of his mate as Donnie gave in to the pleasure again and again.

“Ohhhh fuck,” moaned Donnie, “yes please!” He tensed and shook apart, digging his claws and teeth into his twin’s scales, coming hard and releasing a hot gush down Leo’s hand.

When he was done, melting against his boyfriend, Donnie let go of his wrist and let him withdraw his fingers. He even took Leo's shaking hand and stared into his eyes as he licked his own slick off of it.

Leo, for the first time during this whole ordeal, let out a needy chirp. He blushed, biting his lip, and his eyes dropped to Donnie’s puffy slit, so shiny and pink where it gaped open.

“Oh,” Donnie whispered between licks, “do you want my pussy? Does your cock want to be inside of it?”

Leo found his words. “So much. Does your pussy want my cock to fill it up? Does it want all of my nice hot cum all over it, so full that it overflows? Do you want me to make you a cream pie, Donnie?”

It was Donnie’s turn to chirp and nod, dropping Leo’s hand and leaning in to kiss him deeply. He shifted off of his lap so he could help pull off Leo’s messy shorts.

Before Leo could get too embarrassed about the state of his messy lap, Donnie gently wiped him down with a soft cloth, then took his cock in one experienced hand and gave the tip an openmouthed kiss, swirling his tongue over it.

“How do you want me?” Donnie asked dreamily.

“Face down, tail in the air,” Leo managed to get out with a steady voice. “Show me your pretty ass and pussy, sweetheart.”

Donnie moved to obey. He let go of Leo’s dick with one last playful tug, turning to lay flat on his plastron. Head pillowed on folded arms, he lifted his ass in the air, up on both knees, tail flagging, thighs apart so his brother could see the way his pussy still leaked thin strings of syrupy goo.

Leo could smell him. It was a heady mix of sweetness and earthy pheromones. He growled deeply, getting up close behind him on all fours first, stealing a long, slow lick from his tiny blossoming clit all the way up to his tail, where he bit down gently right at the base. Donnie arched and wailed, legs quaking.

He let go and licked his lips, tasting a little blood. Rising up, he lined up his painfully engorged dick with Donnie’s soaked entrance, and pushed in all the way with a quick thrust.

Both of them groaned loudly at how good their joining felt. Leo bit his lip hard and held onto Donnie’s sides, running his hands over his bridge on both sides. Donnie clenched around Leo’s trapped dick.

“Move now, please!” Donnie begged.

Leo withdrew to the tip and began to fuck his twin so slowly, savoring the way Donnie’s cunt welcomed him, fever hot and fluttering as the softshell experienced involuntary little muscle contractions. His body remembered exactly how Leo made it feel, and it wanted more. And Leo wanted it to last forever.

The slider reached down between their bodies and touched the place where their slits kissed each time he bottomed out. The flesh there was so sensitive. Leo could feel his own tender flesh reacting, and he couldn't help stuffing a finger into the space under his cock, making everything feel so tight, setting off nerve endings he didn't usually touch unless he was trying to make himself drop.

With Donnie to love him and provide him with the most amazing sex, Leo didn't need to touch himself that often. He’d forgotten how good it felt to finger himself while fucking a tight, wet hole. But a fleshlight could never compare to his Donnie's sweet pussy. This was so much better. And he knew Donnie felt it too, every time their bodies bumped together, the little nudge of Leo’s hand brushing against him too. And if he angled it just right–

Donnie clicked and chirped, shaking as he came again from Leo's knuckle grazing his clit. Leo was awed by his twin's capacity for multiple orgasms. It was so hot, so beautiful to watch him let go, feel him tightening around Leo's still thrusting cock.

He picked up the pace, wanting to fuck him good through it. And the first of his own orgasms hit him fast. His jaw clenched and he could only grunt helplessly, filling up his Donnie's sweet pussy with cum.

“Leo,” Donnie gasped, “can we switch our position? I want to look at your face when you cum next time.”

Leo’s breath punched out of him and he relaxed all at once, feeling euphoric. “Of course we can, babe,” he assured him, pulling out and watching his cum dribble out.

Donnie rolled over onto his back and spread his legs wide open, looking down at himself with a smile. “Look at that, Nardo. It already looks so full.”

“I’m gonna make it so pretty,” Leo murmured, rubbing it lovingly. He was still hard, thanks to having next to no refractory period, and he was trying to decide what he wanted to do next.

“Touch yourself for me,” Donnie grinned. “Let me watch you get yourself off. It's so hot. You can glaze me like a donut.”

Leo couldn't hold back a shaky moan and he sat back on his heels, stroking his wet dick and playing with his slit with the other hand. Donnie leaned back propped up against the pillows and watched, licking his lips.

“You look so good, Nardo,” praised Donnie, giving him his best sexy eyes. “Look at that juicy cock, so mouthwatering, shiny from my pussy and your cum. I bet it feels great getting those hands on it. You have such a handsome body. I love watching you make all those beautiful faces when you stroke yourself. You take such good care of your hands but they’re just a little rough from handling your swords. Heh. You have the best firm grip, so nice when you hold me down to fuck me until I squirt all over you. And I bet it feels amazing when you finger your slit, so tight in there with your nice solid cock, just enough room to make yourself squirm when you touch all those sensitive places inside. What I wouldn't give for my own dick, so I could keep you from dropping and fuck you in your tight little cock slit, rub my freaky dick against yours on the inside, make you cum without ever dropping. Maybe I’ll try to grow a tdick, just have to get the hormones right. How would you like it if I grew my own little cock to grind against your leg or your ass when you’re trying to sleep at night?”

All throughout Donnie’s dirty stream of consciousness he’d been rubbing a finger along the center of his pussy, grinding against his digit, the head of his clit flexing and trying to capture his fingertip with each stroke. Leo was watching with wide eyes, licking and biting his poor lips, fucking into his fist and squeezing another finger into the tight space under his dick. He was starting to lose control, little whimpers bursting out of him, and just as he was about to cum, Donnie moved his hand and spread his pussy open with two fingers.

Leo came in long creamy spurts right over Donnie’s soft pink center. His release landed everywhere between his twin’s thighs, all over his pussy and mons, and below, on his puckered little hole and the base of his tail. It even went up as far as the bottom edge of his plastron.

Leo finished with a satisfied churr that Donnie matched. They both admired Leo's work.

“I’m so glad I was recording,” Donnie smirked, pulling Leo close for a kiss. “We’re doing this again soon. But. We're watching the video first.”

Leo, not at all surprised, only kissed back and made a mental note to request his own copy of the video.

Chapter Text

The blonde girl and her ginger girlfriend snorted in tandem, covering their mouths as Tella walked by, obviously trying to hide their smiles and suppress their scornful laughter.

She was used to it. Ignorant people of all types, from her timeline and in this one. New York City, the Hidden City, countless underground bases in a ravaged world. There was always going to be someone who had a problem with her looks. Usually it was her turtle genes that got her the mean comments and the stares, either pitying or cruel.

She tried not to get it to her. By any standards she was a tall, voluptuous woman, and no matter what any haters had to say, she could get a partner of just about any gender or orientation with the right moves. She could go out with no makeup, bald head, wearing the frumpiest clothes, and have admirers flocking to her side with minimal effort. It was all about the rizz, baby.

She kept walking but stopped when she turned a corner, hidden but close enough to hear their conversation.

“Can you believe how big her thighs were?” the redhead remarked. “I’m shocked they even make pants to fit her.”

“How does she even walk? The way they rub together could start a fire!” the blonde scoffed. Tella imagined her tossing her hair over her shoulder.

“She's a freak. I’m sure she wears one of those cloaking brooches. I bet she's not even that pretty.” The ginger sounded disgusted. “C'mon Huntleigh, let's go find somewhere with less ugly people.”

Tella waited for them to leave before muttering to herself, “More like Kuntleigh. And *fewer* ugly people.” She shook her head. “*I* need to go find fewer stupid people.”

She took a deep breath and exhaled slowly. She'd gone out hoping to enjoy the nice day, maybe make some new friends in the new neighborhood, but now all she could hear was the shallow bitches mocking her, their words playing over and over in her head.

Tella stared down at her thighs, squeezing them with both hands, feeling the soft layer of fat and scales on top of pure muscle. She'd never gotten them this big before, never having enough nutrients to gain much body fat past her teen years. Now she had access to everything, and it was ridiculously easy to follow Mikey and Donnie’s dietary guidelines for maximum nutrition and healthy weight gain. She was filling out nicely, they told her. Her coworkers assumed she'd just been sick for a while and was recovering, and had complimented her on looking better and healthier over time.

So why did those vapid bitches’ opinions matter to her? Why did she care if they thought her thighs were too big? She looked damn good in her warm cream colored sweater with a cute brown skirt, and she knew Donnie adored her no matter what she looked like.

Some part of her just wanted to be liked by everyone, she supposed. Even the Huntleighs of the world.

Tella walked to a nearby cafe and ordered drinks and pastries for everyone in the lair. Even for Splinter, although she was still resentful of him after his behavior when they first met. She bought him a fancy tea and some cake. Maybe she could get someone else to give it to him. She was not in the mood to deal with his shit.

She texted the group chat and asked for a portal. Leo made her one almost instantly, and she stepped through into the busy kitchen, setting everything on the table.

“Tella baby, you brought us treats!” Leo cheered, throwing himself at her in a big hug. Her arms wrapped around him instinctively, and she managed a gentle smile.

“I did. Can someone take Splinter his tea and cake?” she requested as the rest of the family gathered around to get their hugs.

“Got it, girl!” April took the little bag and cup after securing her own special Tella hug. “You go ahead and do your thing. I’ll keep the rat busy.”

“Thanks!” Tella smiled, planting a smooch on her head. “You're the best, April!”

April saluted her as best as she could with her hands full, then turned and headed for Splinter’s room.

After everything was passed out, Tella collapsed in a chair and sipped her mocha frappe, picking at the black and white cookie she’d purchased. It wasn't what she really wanted, but she’d been in a hurry and she didn't know what she wanted anymore. Everything she’d considered had her wondering if she was getting too big. And then she wondered if she could even be Dom anymore, if her thighs were too chubby for her masculine drag persona.

Her vision blurred, inexplicably. She blinked hard, rubbing her eyes. “Fuck, did my contacts fall out?” she muttered.

“Hold on, stop rubbing your eyes, dum dum,” Donnie said with soft affection. “Your contacts are right here on your face. I can't tell if they floated out or the eye rubbing did it but I know you know better.” He used two careful fingers to retrieve the contact lenses that were sticking to her face. “There. These are disposable, right?”

“Yeah, and I should have spares in my battle shell,” Tella responded, “but just give me my glasses for now please. I don't want anything in my eyes.” She felt the weight displacement of Donnie rummaging around in her battle shell, then he was carefully sliding the temples of her glasses into either side of her headscarf. “There. Better?”

Tella bit the corner of her lip and nodded, staring at his handsome and kind face. She extended a hand and lightly caressed his cheekbone with her thumb. She wanted him to touch her again, but at the moment she didn't feel like she could ask. “Yes. Thank you. Um. Can we go talk somewhere quiet?”

Donnie leaned into her touch and she heard a quiet churr. “Of course.” His smile was sweet, inviting. “Lab?”

Tella nodded, glancing at her other siblings. “I will spend some time with all of you later, I promise!”

Leo was the first to kiss her right in the middle of her forehead. “I’ll be around if you need me!” He patted her arm.

Mikey and Raph each gave her another hug before she and Donnie left for the lab. Their warmth stayed with her, comforting.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Tella pulled off her battle shell, gauntlet, and sweater as soon as the lab door locked, putting them up on their dedicated hooks/shelves (carefully hanging the sweater on a padded hanger first) before kicking her shoes off and shimmying out of her skirt. She was wearing a cute bra and panty set, pale pink with white accents, and her tail poked out of a hole in the back of her panties. She took a long drink of her frappe and stashed it in the mini fridge before taking a seat on her chair next to Donnie’s.

Her boyfriend removed his battle shell and gauntlet too, and she watched him as he took off his belt and wraps, swapped out his goggles for a pair of pink cat ears headphones, and tugged off his shorts after a moment too, revealing a cute little pair of thong underwear underneath. Without conscious thought, Tella stared at his lower half with admiration and appreciation. He had such nice thighs, slimmer than hers but just the right ratio of fat to muscle. They looked so kissable. Her face burned with a mixture of arousal and shame.

“Tella, love?” His tone was so warm and a little husky, bringing her attention to his face. His gorgeous, loving face. He was looking at her the same way she felt about him. And she wanted to forget about her insecurities and just make love to him, hold him and be held, but she knew he wouldn't let it go. They were here to talk, after all.

“Donnie,” she began, “you love me. That's not a question. You love me the same way I love you. Endlessly and completely. So. I trust you with my entire being. I have an honest question, and I would like an honest answer, if you wouldn't mind.” She blinked slowly. “But. Would you hold me?”

Donnie was at her side almost immediately, climbing up and sitting on her lap so he could wrap both arms around her and cradle her head against his shoulder. She hunched over and held him back, letting herself relax into his embrace. His scent and warmth dissolved some of her tension. He felt like home.

“I have you, beloved,” he whispered, nuzzling her cheek. “I love you always.”

“I love you so much,” Tella whispered back. “I. Was wondering. Do you think my thighs are too big?”

Donnie froze. He bluescreened. He sat motionless for a full minute before speaking very slowly. “You. Want to know. If your thighs are too big. What. How. I–I don't understand. Your thighs are perfect. They always have been and always will be. Bigger thighs mean more surface area to squeeze and kiss and lick and bite. Your thighs are a gift from the universe. Who told you they were too big?”

Tella’s voice shook. “I was having a really nice day, walking in the Hidden City. Um. These two stupid shallow bitches. I can't make this shit up, one was named Huntleigh. They were laughing at me and started their shit talking when I turned the corner. I–I *know* they're just bullies and they don't matter but they–they hurt my feelings–” Her voice cracked on the last word and she pulled her glasses off to wipe her eyes with the heel of her hand. “I don't know why I even care! They don't even know me. Why am I upset about it?”

“Hey. You are worth so much more than they ever will be, Tella,” Donnie soothed, kissing her right between her eyes. “I know it hurts. You just want people to like you, and when they're mean for no reason, it’s not fair. But guess what? They will never get to touch you. They're not worthy of you. These thighs? They're yours, and as your boyfriend, they're mine too. Unless you say otherwise.” He smiled at her, eyes crinkling. “It's fine if you're not up for it, but if you want you can sit on my face and let me show you just how much I love being suffocated by those beautiful thighs.”

Tella nodded, using the tail of her headscarf to dry her face. “That sounds really, really good,” she told him, not quite able to manage a smile. “Let's do it.”

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Donnie reclined on the bed, removing his mask and setting it on the nightstand. He watched Tella unhook her bra and step out of her panties, showing him her beautiful soft tits and her shiny little pussy, tucked between those plush thighs he loved so much. He opted to leave his own underwear on for now. As small as it was, the thong would only serve to accentuate his bulge if he dropped. He knew she liked to see the outline of his glans through the straining fabric, watching the way each little appendage moved to grope blindly, searching for her warm wet cunt to bury itself inside.

Tella crawled up the bed beside him before straddling his chest for a moment, letting him get two handfuls of supple, strong thighs to massage and play with. Her head hung down, eyes locked onto his face, studying his microexpressions as he rubbed her markings and churred, content.

“You’re really enjoying this,” she marveled, resting her hands lightly on top of his so she could feel his muscles and tendons working, feeling what he felt. “You're not one to give false compliments. Same as me. And the greatest compliment is how you look at me. I…feel better now.” Her mouth turned upward at the corners, ever so slightly. “But I still need you to keep doing this.”

Donnie moved a hand to her round ass and gave her a little squeeze there. “Come on up, on my face, missy. Let me feel your thighs around my head.”

Tella moved cautiously. She was still bigger than him and didn't want to hurt him if she moved wrong. She settled down over his face, letting the warm pudge of her thighs press against the sides of his head.

“Is this ok?” she asked, caressing the top of his head.

Donnie breathed in her musk and the sweetness of her slick, going a little cross-eyed as it hit him somewhere deep in his brain, satisfying some primal need. “This is fantastic! You can squeeze me tighter if you need to. I’ll slap your ass or your thigh if it gets to be too much.” His voice was a bit muffled but dreamy and lovestruck.

Tella pressed her thighs a little more firmly against him. She heard a faint moan followed by the schlick of him dropping into his satin underwear. Oh, he was really into this!

As he began to lick her open, his hands moved on her, lightly stroking her scales anywhere he could reach. She felt his tongue brush against her clit, and it tried to close its little blossom around the tip of his tongue. Even her clit was carnivorous. She liked to think if she'd grown a dick, it would have become a behemoth by now, a big heavy satisfying weight between her legs. She knew Donnie’s was nothing to scoff at, and he was still growing. She might just have to reward him after this.

She was already drizzling Donnie's lips and chin (his markings there were forming nicely, handsome and bright) with her nectar. She let herself breathe deeply, audibly, soft little moans building in her throat. He was pushing his tongue into every fold of her pussy, poking all the little indents and crevices. She hissed in surprise as he tongue fucked her pee hole before moving down. She’d never let herself be touched there in the apocalypse, deathly afraid of anything resembling an infection, since antibiotics were so scarce. But. They were in a time of abundance and if need be they could take some from a pharmacy or order fish antibiotics on the internet. So. It wasn't actually that unpleasant, just really intense. She’d file that as a maybe in her mental kink checklist.

Donnie’s snout was buried in her cunt, slurping up her slick and darting his tongue in and out of her vagina. It was so slippery and hot, and she wanted more.

“Finger me,” she gasped. “Suck on my clit and–and finger my ass and pussy. If you make me cum I’ll suffocate you and do anything you want.” She was desperate to be full and she was sure he would be so good at this.

Donnie hummed and dragged his flat tongue up to her clit, making shapes on the tip as he dipped his fingers in her slick. Then a finger of one hand ended up wiggling its way past the tight muscle ring of her ass, and two fingers of the other hand entered her pussy opening, burying themselves deep.

He applied suction to her clit and let the vibrations of his humming flow through her via his tongue pressed to the underside. Tella squeaked and chirped, thighs trembling, and she had to use both hands to brace herself against the headboard so she didn't break his neck with her full body weight. Her knuckles turned white as her grip tightened.

She began to rock against his face and fingers as he found a rhythm and quickly brought her to the brink. He prepared himself for a flood, inhaling deeply and then just holding his breath.

Tella came with a series of clicks and grunts, followed by whimpers as Donnie made sure to get every shudder and squirt out of her. She was a little overstimulated but she had the vague impression of a ravenous Donnie licking the plate clean after a good meal.

She moved off of his face and let him take some good deep gulps of air, and then she wiped his face thoroughly so she could kiss it all over. As she lay flat over him, carefully supporting herself on her knees so she didn't crush him, she could feel the damp pressure of his erection through the satin, right up against her plastron.

“Do you want to fuck my thighs?” Tella offered, in a hushed conspiratorial tone like she was offering him forbidden fruit. She watched his face bloom into a beautiful blush, and met his smile with her own fierce grin as he nodded fast.

She adjusted her position, lying on her side as he spooned her from behind. He pulled his thong down just enough for his big needy cock to spring free, reaching out with its prongs. She moved her leg so he could slide in, then closed her thighs around him, letting him slot into place. His shaft pushed against her closed slit, and her sensitive clit poked out, erect enough for him to bump it with each thrust.

He held her torso tightly and moved, rocking gently, letting himself feel how smooth and soft she was. His cock flexed open with each thrust forward, and closed with each glide back. He strained to whisper as close to her tympanum as he could get, elongating his neck. “I will never get over how good you feel around my cock or my face or any part of me. Your thighs are the best gift to the world, but the world doesn't get to keep them. They're for us. For me. Anyone who dares disparage them will regret they ever dared insult my Tella. I am in love with you. Every part of you is precious and beautiful and delicious. I hope my last breath is between your thighs or buried in your chest or against your sweet lips. My love, my perfect Tella.”

Tella’s breaths hitched and she hugged his arms that held her so tight. “Oh Donnie, Sweetness, you stole all my words!” She tightened her thighs around his length, making him groan and turn his face into her carapace. He moved a little faster, desperate, so close to where he needed to be. He shifted his angle to bump against her clit a little more.

“Aaaahhhh!” she cried out, soaking him with her release. Donnie’s rhythm grew frantic, and then he painted her thighs and slit with hot pearls of cum, shaking against her back.

“I love you,” Tella moaned. “I love you so much.”

They caught their breath, let their heartbeats even out, cleaned up as best as they could. Then they let go and Tella rolled onto her other side so she could hold Donnie cradled against her chest.

“Thank you. You have no idea how much better I feel. You make me feel so loved.” Tella's voice was honeyed, saturated with gratitude and adoration. “I think I just really needed you. You make everything better.”

Donnie looked up at her, eyes shining. “You can have me whenever you want, you know. You don't have to choose between me and, well, anything. I’d follow you anywhere. Or you can just come to me anytime. I'm just happy I’m yours and you're mine.”

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

When Donnie and Tella emerged, freshly showered, Tella decided her day was better spent with family anyway.

She stayed for dinner and Game Night. Mikey served homemade Mexican food with special sensory friendly dishes for the softshells. They played different board and card games, with music playing in the background, SHELLDON picking the tunes. Tella wore a soft hoodie and sweatpants she’d left in the lab for when she stayed over, and when they talked her into a sleepover and a turtle pile, she didn't fight them. She really needed her family.

When everyone was asleep, Donnie opened one eye and signed some things to SHELLDON. They had a silent conversation. When they were finished, Donnie relaxed between Tella and Leo and fell asleep.

The next day, April and Cassandra went to the Hidden City and found the two bullies who’d mocked Tella. While the older softshell was at work, the Hamatos interrogated and threatened Huntleigh and her girlfriend Breighlynn. (“Of course you both have awful names. Eyeroll.” Donnie was not impressed.)

Tella came home to her apartment to find an envelope stuck to her door, and a gift basket full of her favorite fruit and chocolate as well as gourmet coffee. In the envelope was an apology letter praising her good looks among other things. Someone had included a Polaroid photo of both girls tied to chairs, covered in Sharpied caricatures of themselves, both on their clothes and their exposed skin.

She just smiled, sat in her favorite spot on the couch, and enjoyed her snacks.

Chapter Text

Mikey slept plastron down, limbs completely limp, bare ass naked. His face was turned to the right, mouth parted slightly, breathing directly into Leo’s face. His tail was up, and the slider could smell his arousal along with the sweetness of his breath. Leo had been counting on this when he offered to stay with Mikey until he fell asleep. He knew his little brother was prone to frequent wet dreams and didn't bother to wear anything to bed anymore. He’d offered to strip down too, so it wouldn't be so awkward.

Mikey had smiled slyly. “Whatever you’re comfortable with, Leo.”

It wasn't that he’d given Leo explicit permission. It was more of a vibe. Mikey’d posed himself in such a way that Leo would be able to tell immediately when he was aroused. He liked to give others opportunities rather than flat out ask them for sex. And Leo knew from conversations with his blunt autistic brother that Donnie had taken advantage before. He’d confided that Mikey kept himself prepped and ready, so it was easy to slide right into his tight little ass and take him. Sometimes after the deed, Mikey would roll over and let Donnie ride him, and he really liked being eaten out when he was still half asleep. He would wake up if Donnie got his tongue inside of him, and he always rewarded him with a really good breakfast.

After that conversation, Leo had pinned Donnie to the wall in the softshell’s room and fucked him slowly, whispering dirty thoughts between bites to his neck. They’d both gotten really worked up from talking about Mikey. They’d almost gotten caught by Raph, who’d been doing nightly check-ins, but then their big brother got distracted and they were able to finish making each other cum and clean up the evidence before slipping into bed and pretending to sleep. Just in the nick of time, too. Just as their breathing was starting to even out, Raph had peeked in to see them cuddling under Donnie’s big weighted blanket.

(He hadn't said anything, but Raph was also not stupid. He always knew when his little brothers had been fucking. He waited patiently. It would be his turn soon.)

Leo held back a moan as he dropped, remembering. He slid a shaky hand up Mikey’s thigh, squeezing when he reached his round buttocks, then dragging a finger between those deliciously firm cheeks, finding his opening. Oh, Donnie wasn't kidding. Mikey was wet, still tight but welcoming, practically sucking his finger inside.

Leo moved to straddle Mikey, still fingering him for a moment, wanting to be sure. The box turtle lay still; the only indication of what he felt was slightly quicker breathing and a twitching tail. When Leo withdrew his digit, Mikey let out the tiniest whimper.

“Shhh baby, I’m gonna make you feel good,” soothed Leo, lining up. As the tip of his cock breached Mikey's hole, they both moaned quietly.

Leo took his time sliding in, giving Mikey an inch at a time, feeling his baby brother’s walls tighten around his shaft as he struggled not to bottom out quickly. He wanted to be gentle and make it last. He took slow, deep breaths and fought to control himself. He really didn't want to wake Mikey yet and ruin the experience.

Mikey was panting louder now. He shifted beneath Leo, lifting his ass up slightly, and the sound of him dropping made his big brother churr. Leo reached under to wrap a hand around him. Mikey moved suddenly, impaling himself the rest of the way on Leo. Then he started fucking Leo’s fist.

With a strangled groan, Leo gave in and started moving faster. Waves of heat and pleasure flooded his body. He squeezed Mikey’s dick tighter as he thrust into him. They both came, and just as they were finishing, the door opened and Donnie and Raph walked in.

“Gorgeous,” Donnie muttered, shutting the door and locking it. “Is he still asleep?”

Leo let go of Mikey’s cock and pulled out, moving slowly so as not to startle him. “Think so,” he panted, flopping onto his back next to him. “Why, you want a turn?” He met Donnie’s eyes and licked his hand, tasting Mikey's cum.

Donnie shivered. He glanced at Raph. “I think you should go first, Raphala. You haven't done this yet.”

Raph was already undressing Donnie, getting down on his knees in front of him and carefully unbuttoning his pajama top with big awkward fingers. When he tugged his pants down, fingertips brushing Donnie’s hips, the softshell dropped in his face, wet and needy.

“I’ll take Mikey if you go let Leo take care of you,” Raph promised, leaning in to kiss the tip of his dick. Donnie clamped a hand over his mouth to stifle the sudden whimper, and he nodded quickly.

“C'mere Dee,” Leo coaxed, making grabby hands. Donnie crossed the room and let his twin pull him close, kissing down his body.

“Just relax,” Leo told him with a sultry wink before swallowing him whole.

Next to them, Raph picked Mikey up and flipped him over effortlessly. It was easy for Raph to tug his shorts down and hold himself over Mikey’s glistening dick, forcing himself not to drop so he could take the box turtle’s full length inside of his cock slit.

Mikey’s eyelids fluttered open, but his eyes were glazed over, dreaming. He mumbled slurred syllables that were almost “Raphie” and spread his legs wider.

Raph’s expression softened into adoration and he nuzzled Mikey’s cheek. “Shhh, sleep, Mikey. Raphie's right here.” He churred deeply, cock warming him until Mikey let out a quiet churr and drifted off.

The snapper moved slowly at first, but the delicious burn of his baby brother's big cock sliding against his own trapped erection inside his slit made him start to slip into a near frantic state. The sucking and slurping noises beside him only made Raph feel hotter and more aroused.

“Fuck,” he grunted, keeping his eyes on Mikey's slack face as he rode him. Slick began to pour out of him onto Mikey’s shaft and slit, making everything feel overwhelmingly better, and Raph struggled not to drop as his internal muscles burned.

“Raphie,” Donnie moaned, “look at me.”

Raph glanced over at Donnie and almost came right then. The softshell was drenched in sweat as Leo alternated between sucking him off and licking secret messages on his sensitive glans, and he couldn't help making pathetic little chirps and whimpers as Leo fingered his ass. He gave Raph a half-lidded, loving look and an open-mouthed smile.

“Big Daddy, you look so good riding Mikey’s cock like that–mmh fuck–so hot, I could just eat you up!” Donnie praised. “Think–gah! Leo!--think I’m gonna cum now! Can you hold my hand?”

Donnie held out his shaking hand, panting and starting to tense up, eyebrows pulled together in an expression that signaled his imminent release. Raph immediately wrapped it in his large fingers, squeezing gently. He was rocking automatically, letting Mikey hit his most sensitive nerves as their cocks slid together inside of him.

The extra stimulation of Donnie’s heated skin against his hand set off Raph unexpectedly, making him whimper loudly as he came in a flood. He’d never done that while not dropped, at least not while awake. It was so intense that he cried, tears overflowing to wet his skin as his trapped cock pumped out seemingly endless cum.

Mikey came too, spurting into Raph and causing him to gush from the sheer volume. It was almost too much. Raph squeezed Donnie's hand tighter and felt an answering squeeze. Through a blurry film of tears he saw Donnie’s rapturous face. He blinked hard to clear his vision. He and Donnie watched each other as they gradually came down from their climaxes.

Leo pulled off of Donnie’s dick and licked his lips. “Wow, that was really hot!” He moved up to give Donnie a kiss, and his twin reciprocated the kiss with teeth and a growl, biting Leo’s mouth possessively. The softshell's free hand found Leo’s ass and tail and he shamelessly groped him.

Raph gave Donnie one last squeeze before letting go of his hand, and began the process of pulling off of Mikey. He felt overstimulated, so the sensation of their cocks sliding was almost painful now. It was a relief to be free.

Donnie and Leo broke apart. “C’mere Raphala,” Donnie urged sweetly, “let us get you cleaned up.”

The twins did a very thorough job of licking him clean, inside and out. Their warm tongues felt soothing. Raph couldn't help dropping when Donnie’s extra long tongue dipped into his slit and swirled around his tip.

Donnie swallowed him down with only a little difficulty, mainly from his girth. Then stayed still for a few minutes, giving him affectionate little scritches anywhere he could reach with his claws, just soothing his cock with his warm wet throat and providing gentle stimulation until his nerves felt less like they were on fire.

When Raph relaxed completely, Donnie pulled off and patted his plastron. “Feel better now?” He sounded drowsy but full of so much love for his big brother. It made Raph feel all tingly inside.

“Much better, thank you!” Raph replied, scooping him up in a quick embrace. He didn't want to push it but Donnie didn't seem to be in a touch averse mood.

Donnie snuggled close for a minute before wiggling free. “I suppose it's time to get Michael cleaned up,” he remarked, not at all sorry to be taking on that task.

As Donnie headed over to Mikey, Leo seized the opportunity and took his twin's place in Raph's arms.

“Hi Big Daddy, time for cuddles?” he grinned.

Raph churred happily and held him close.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Mikey woke up to a tongue between his legs, and a churr that was distinctly Donnie’s from the slight hissy undertone. He felt tingly and very well fucked, and his cock was still out and wet with slick and cum, which meant he must have been inside of someone recently. He could smell Raph and Leo nearby.

His hand drifted down to scratch the top of Donnie’s head through his mask. “Such a good boy, Donnie,” he praised, then yawned. He was still a little sleepy.

Donnie stopped what he was doing to throw his arms around Mikey’s thighs in a tight hug. “You’ve been so good for us, Michael,” he replied, kissing him right next to his puffy slit. “Just relax and let me take care of you.”

Mikey shivered and stroked Donnie’s cheekbone with one thumb. “K. Thanks, Dee.” He watched as Donnie resumed his actions.

Donnie licked him up and down methodically, taking his time cleaning off the fluids that tasted like Mikey and Raph. He left wet kisses all over his pelvic area, lapping up anything left there. Then he moved down to Mikey's ass and tail.

Mikey gasped and shook as Donnie went deep with his tongue, caressing his inner walls and cleaning out as much of Leo’s cum as he could reach. He was stroking Mikey’s tail like a cock, twisting his hand and squeezing on each upward stroke.

“Donnie!” Mikey moaned, twitching. “Don't stop!”

Donnie winked and kept going, moving his other hand to play with Mikey’s cock and slit. He was having a great time. It was one of his favorite things, waking up his little brother by eating him out. He enjoyed the praise, sure, but the activity itself was fun and made his brain buzz with pleasure.

He knew his kink was a little weird, but as long as he and Mikey enjoyed it, it was harmless. And apparently Leo and Raph liked it too. Who knew it would become a family thing?

He’d been at it for several minutes now, focused on the sounds of Mikey panting and moaning, the delicious smells and tastes, the feeling of Mikey's thighs pressing against the sides of his head now that he was actively tongue fucking him. He was so lost in it all that he missed Mikey’s orgasm until his hand was coated in cum and everything was shaking like an earthquake. It took him a moment to realize it was because he was still tongue deep inside of his brother and shaking along with him.

He pulled away and licked his hand and Mikey’s cock clean. Then kept going. It took several rounds for Mikey to beg him to stop, and by then Donnie was in such a feral state that Raph had to hold him back so he wouldn't bite Leo for daring to get between him and his delicious meal. Brother. Same difference.

Raph distracted Donnie by playing with his cock and talking dirty, and he and Leo pinned him down and made him cum until he passed out.

Much later, after they'd all slept and recovered, Mikey cooked everyone a delicious brunch and they made plans for next time to include all four of them.

Chapter Text

Donatello crouched behind his father's chair and counted the pocket change he’d been collecting during their trips to the surface that Papa definitely didn't know about. He’d been picking up coins he found on the ground while his brothers were busy playing basketball with April O’Neil, their new human friend they'd just met three months ago.

He liked her. He wasn't sure what that meant, exactly. Donatello had always had trouble with identifying feelings. Alexithymia. It was a word he’d seen while scouring the internet for information about his unique condition that none of his brothers seemed to have. Well, not in the same way. Autism. Another word that described Donatello. He was bad at feelings and bad at processing stimuli. His over- and understimulation issues, his literal thinking, the way he didn'tunderstand social cues or facial expressions, his need to correct errors to a fault, his aversion totouch and bad textures/flavors/smells. They were all symptoms of how his brain was configured in a different way.

Donatello knew that April was pretty and loud and smart. She liked weird things, nerdy things, anything she could learn from and play with and talk about. She was like Leonardo in some ways and like Donatello in others. The loudness, the prettiness, that was just like his twin. The brains and the need to seek out knowledge was all Donatello.

Sometimes he thought about what it would be like if April loved him. He was barely even friends with her, because his brothers were all so much better at socializing and getting her attention. But if he could get past the social awkwardness barrier and find a way to impress her, maybebshe would want to spend more time with him. Maybe she would at least like him.

Donatello loved his brothers and his Papa so much, even if he was bad at showing it. But he really, really wanted a best friend who was just as smart as him, who could keep up with his thoughts and would understand if it was a bad day and he didn't want anyone to touch him. Someone who would respect him and not gang up on him the way his brothers often did when they wanted him to behave a certain way. Was it too much to ask to be truly understood and loved for who he was?

He had a plan. He was going to sneak off to the bodega and buy April some candy. He knew she liked fruity and sour flavors, so it should be easy to find something for her. He could hide it in his hoodie pocket until the next time they played together, and even if she was too busy to talk, he was sure she would enjoy his offering.

He couldn't wait to see her reaction. If he was lucky, she would do her happy flappy, as she Donatello wished he’d brought someone with him. He was perfectly capable of finding his way to the bodega unassisted, but the manhole cover was heavy and he nearly fell off the ladder trying to push it up and out of the way. When he stumbled out of the sewer into the deserted alley, he winced at the sound of traffic a few streets away. Everything was too loud up here.

He’d shoved his feet into sneakers that were too big, stuffed with pages of an old newspaper and tied tightly. They chafed against his heel and made him want to yank them off and scream. But he had to wear shoes inside the bodega. That was an important rule. No shoes, no shirt, no service. He was also wearing pants because he was pretty sure that was a rule too. Even if it wasn't on the sign. He’d never seen anyone in the bodega with no pants on, unless they were wearing a dress or skirt. He didn't want to get yelled at and chased out, especially since he was a turtle and Papa said humans wouldn't understand how a turtle could be a person.

April understood turtle people just fine. Maybe it was because she was a kid and didn't know better.

The door to the bodega was propped open for a delivery person who was unloading bottles of different colored liquids. Donatello wandered in and walked directly over to the candy section, where he found April's favorite sour candy. It was shaped like different types of fruit, and he had enough money to buy the bigger bag. He’d counted his coins multiple times to be sure.

Taking the bag, he tiptoed over to the counter and lifted the bag up for the cashier. The man behind the counter raised an eyebrow but didn't comment on his size or skin color. “That will be 8 dollars, child.”

Donatello reached into his pocket and pulled out handfuls of coins, stacking them by denomination. When he got to the pennies, he grouped them by fives.

“Good job,” praised the patient cashier, a smile forming on his previously somber face. “You will do well in school. Keep learning.” He collected the money and placed the candy in a sturdy plastic tote bag that zipped shut. “I will be watching for you.”

Donatello beamed at the praise. “Thank you!” He was proud that he remembered his manners that Splinter had taught him. Taking the bag, he turned and left the bodega, finding his way home.

It was late and he was very tired, but he managed to slide the bag under the bed before changing into his pajamas and climbing in next to Leonardo. His twin welcomed him with a sleepy hug. Donatello churred quietly and snuggled close, falling asleep.

The next day, Leonardo demanded to know where he’d been. “I woke up and you were gone!”

“Shhh, don't tell.” Donatello showed him the bag. “For April. I want her to like me.” He didn't know why that admission made him blush.

“O’course she likes you!” Leonardo exclaimed. “You're Don Don!”

“Donatello,” he corrected, but he couldn't help smiling. Leonardo loved him and always thought he was great. Donatello hoped April thought the same way.

“C’mon, that's too long! Donnie for short?” Leonardo stared at him with wide shining eyes that made his tummy feel weird. “Please? You can call me Leo or Leon or Nardo.”

Donnie sighed. “I s’pose I can allow it. Only ‘cause you're my best friend.” He patted his brother’s arm. “You can't tell anyone about the candy. It's a secret, Nardo.”

Leo broke into a big grin, bouncing. “I won't tell, Donnie!”

It was raining so they didn't go visit April today. Raphael gave them cereal for breakfast and they spent most of the day playing. After some consideration, Donnie agreed that Raphie and Mikey could have nicknames too. It was faster and easier to say.

Papa put on Lou Jitsu and they showed him their best ninja moves. Papa praised them all and went out, coming back with pizza. Even if it was a little wet from the rain, it was good.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The four brothers met up with April at a deserted playground covered in graffiti. Most kids weren't allowed to go there, but April’s mom worked at a hospital and her dad was gone a lot, so she was alone after school for a few hours. Her parents trusted her to be good and stay out of trouble. So naturally, she did all her homework in class so she could go play with mutant turtle kids in a sketchy area right after she got home.

April spent a lot of time playing with three of the four turtles. Donatello, the quiet purple kid with glasses, usually brought a book or a fidget toy and hung out on a bench, pretending not to watch her. But she could feel his stare when he thought she wasn't paying attention. She knew he cared, even if he didn't come play with them.

Today he seemed more…bouncy. Nervous or excited maybe. He wasn't even pretending to play with the Rubik’s cube he'd brought along, leaving it next to him on the metal bench. He watched her, eyes sparkling, legs kicking in a way that told her he was waiting for the right moment to do something.

April glanced at Donatello's brothers to make sure they were having fun safely (she was the oldest, after all) and approached the purple softshell.

“Hey, Donatello!” she greeted him with a smile. “You look like you're just full of energy today! What's up with you?”

Donatello’s smile told her he was pleased to see her. He pulled out a sandwich bag from his hoodie pocket and presented it to her with dramatic flair. “Hello, April. This is for you! It's sour candy.”

April took the baggie from his outstretched three-fingered hand and squealed when she saw what was inside. “Omigosh Donatello! Thank you!” She flapped her hands and spun around in circles until she was dizzy, giggling. “It's my favorite!”

Donatello hopped off the bench and flapped his hands with her, although he didn't spin. Instead he caught her by the arms when she started to fall over, gently lowering her to the ground. “Uh oh. Be safe!” he warned her. “I’m not big enough to carry you!”

“Don't worry, I won't get hurt!” April grinned. She opened the baggie and tasted some of the candy. “Want some?”

Donatello sat beside her and took a purple candy, licking it and making a sour face. Then he popped it in his mouth. “Very sour!”

They shared the candy and talked quietly. After a few minutes Donatello gave her a serious look.

“April? Do you want to be my best friend? If you do, you can call me Donnie. That's what Leo calls me. He’s also my best friend.” He tried to keep his face neutral but his eyes lit up hopefully.

April couldn't contain her joy. She leaned in and kissed him on his smooth green cheek. “I would love to be your best friend, Donnie!”

Donnie made a noise halfway between a chirp and a happy sob. He wasn't one for public displays of affection, but he was just so happy! He threw his arms around her and pulled her into his lap, nuzzling her shoulder.

After a moment his brothers came running over. “Donnie?” “What's goin’ on, Dee?” “Hey I wanna hug!”

They all ended up in a group hug, and Donnie couldn't stop smiling.

“April is MY best friend now,” he announced proudly.

Leo leaned close and gave him a wet kiss on his other cheek. “Well I was your best friend first!”

“We’re all friends, ok?” April placated, trying not to hurt anyone's feelings.

“But we're the best!” whispered Leo, too quiet for anyone but April and Donnie to hear, smirking.

“Hey, I want candy!” pouted Mikey, noticing the empty baggie.

“Raphie’ll get you candy,” Raph told him.

They all got candy.
